Video Communication & Modern Businesses
In an era defined by rapid technological advancement and shifting business landscapes, video communication has emerged as a pivotal tool for modern enterprises. Platforms like Twilio, Zoom, Google Meet, and Jitsi have revolutionized the way businesses operate, enabling seamless collaboration and communication regardless of physical distance. The COVID-19 pandemic underscored the critical importance of these tools, as companies around the world were forced to quickly adapt to remote work environments.
During the height of the pandemic, these video communication platforms played a crucial role in maintaining business continuity. Zoom, for instance, saw a massive surge in users as companies turned to its platform for virtual meetings, webinars, and conferences. Similarly, Twilio’s cloud communication solutions enabled businesses to quickly implement and scale their communication strategies, ensuring that employees remained connected and productive. Google Meet and Jitsi provided secure and reliable video conferencing capabilities, allowing teams to collaborate effectively in a virtual setting. These platforms not only kept businesses running but also paved the way for a new era of remote work and digital collaboration.
The current Video communication providers can be categorized into 2 broad categories. One category has those who provide ready-to-use video meeting solutions like Gmeet & Zoom, and another category has those who provide all the tools and technologies like Twilio & Jitsi for building custom video meeting solutions. The second category who provide tools to build video solutions can further be categorized into 2 sub categories. One subcategory is Jitsi which provides ready to use self-hosted video meeting solutions including the frontend, backend, media server, horizontal scaling, etc and the other subcategory is the CPAAS/ Video SDK providers like Twilio which provides a scalable backend service along with frontend APIs to build video applications.
All the above-mentioned categories and subcategories have their strengths and weaknesses for a specific business use case. But in general, a requirement can be divided into the abovementioned categories / sub-categories. Accordingly, an option can be chosen from all the available options in that category/sub-category. To keep this post clear and crisp, we are going to discuss more on the second subcategory of the second category, i.e. Twilio as a Video SDK provider and the impact of its EOL (End Of Life) on its existing customers as well as the sub-category/category as a whole.
Twilio Video Discontinuation & Changing Landscapes
The recent announcement by Twilio regarding the discontinuation of its Twilio Video service marks a significant shift in the landscape of video communication platforms. This decision comes amidst a rapidly evolving market, with new players entering the field and existing ones constantly innovating to meet the growing demands of users. While this change may initially cause concern for businesses relying on Twilio Video, it also presents an opportunity to reassess and adapt to the evolving needs of modern communication.
As businesses navigate this transition, it’s important to recognize that the discontinuation of Twilio Video does not signify the end of innovative video communication solutions. Instead, it signals a dynamic market where companies must remain agile and open to exploring new technologies. This shift also underscores the importance of choosing a video communication platform that aligns with the long-term goals and requirements of the organization. By carefully evaluating the available options and selecting a platform that offers both stability and scalability, businesses can continue to leverage the power of video communication to drive growth and success in an ever-changing landscape.
Possible reasons that could have led to Twilio Video Sunset
People who understand how Video technologies work and how complex it is to build a stable enterprise-ready video application, can’t ignore the importance of correct decisions early on related to the core components of the video application. If one goes wrong here at the early stages, there is a good chance of negative impacts in the later stages related to stability, scaling, future feature enhancements, etc. I assume something like this, i.e. some incorrect decisions in the early stages of the Twilio video, would have happened with them as well. I wish to share a short story from my own experience before moving on.
We who followed WebRTC from its early days i.e. from 2012-13 time, can’t forget the promise made by an open-source WebRTC media server named Kurento to the developer community at that time. It was the leading media server at those times with a promise of media forwarding(SFU), merging(MCU), and real-time post processing(with OpenCV) all combined into one package. It was theoretically the perfect media server that could change the world of media scaling and real-time processing forever. I had used Kurento for some of my personal/commercial projects in 2014-15 and I was also super excited about its prospects and possibilities. It was developed by some students and professors at a Spanish University and this open-source package was maintained by them as well along with other contributors.
But in the year 2016-17, after using this media server for 1 -2 years in some commercial projects, I realized that it is hard to manage and scale this media server. It is resource-guzzling as well as slow and less capable of handling concurrent meeting rooms
in larger numbers. It had some core features like ICERestarts were missing as well which are a necessity if wish to deal with bad networks. Therefore, a realization came to us in the year 2019 that we need to move our commercial project to a better media server if we wish to scale it to larger numbers.
The interesting part here is that Twilio bought Kurento for its promises in the year 2017 and built Twilio video on top of it. They bought it for $ 40 million (I read it somewhere back in 2017!) and spent a good amount of money afterward to make it Twilio Video. I think they realized something similar in 2023 which we realized in 2019 and thought of moving on.
I am not sure if this was the primary reason or not as I can only assume what could have happened. But I think the decision to buy Kurento 2017 and deciding to build a Twilio video on top of it may have some role to play in the decision to Twilio video Sunset.
Key learning from this incident
Anybody planning to build a video application should take a learning from it. The key learning is to avoid doing the fundamentally wrong things early on which may have catastrophic impacts later. Therefore it is critical to have good video application professionals (like us!) on your side who have sufficient experience with your kind of use cases early on, to make the right decisions that is beneficial for you and your application both in the shortest as well as in the longest term.
The Beginning of Search for a Twilio Video Alternative
In the realm of real-time communication, Twilio Video has established itself as a go-to solution for many businesses. However, as it is sun-setting its service for some reasons, we need to consider various factors when exploring alternatives. The importance of reliability, scalability, security, and ease of integration cannot be overstated in this context.
Reliability is paramount in any communication system. Look for alternatives with a proven track record of uptime and minimal disruptions. The best way to check reliability is by building a POC to check the performance of the provider with some edge cases like how the audio/video connection performs when the network degrades OR does the video freezes for a user when switching between 5g / Wifi. These scenarios tell about the depth of the provider concerning building video applications.
Scalability is not a deal breaker if your use case doesn’t require 1000s of users in 1 room or 1000s of rooms concurrently running with 10s / 100s of users in each room. But if you have a use case that needs either 1000s of users in 1 room or 1000s of concurrent rooms, then do check the scalability aspects well. A good practice is to as for load test reports which was done by the provider. The best option is to run the load tests yourselves with a POC application to check the scalability for yourself.
Security is non-negotiable, especially when dealing with sensitive information. Look for alternatives that offer end-to-end encryption and comply with relevant regulations like GDPR and HIPAA. Are they providing E2E encryption in case it is a need for your application Or can they store the recordings in an encrypted format in case of a need? These are some of the questions that need to be asked to the provider before deciding on the security aspects of it.
Ease of integration is another important aspect that can make or break your video application. If it takes too many API calls to achieve a small thing or there are important APIs that are not available for your use case then it is not worth considering the solution even if it offers the above 3.
Based on the above parameters, we can consider 2 types of solutions that can become a Twilio video alternative. One is an open-source media server-based solution and another is a proprietary solution provided by a commercial vendor. In this post, we are going to explore both alternatives in a detailed manner.
Open Source Twilio Video Alternatives:
Open-source video communication solutions are software platforms that enable users to communicate through video conferencing, messaging, and collaboration tools. Unlike proprietary solutions, open-source solutions provide the underlying code for free, allowing users to modify, customize, and distribute the software according to their needs. This openness fosters innovation, as developers worldwide can contribute to improving the software, leading to rapid advancements and feature enhancements.
One of the key benefits of open-source video communication solutions is their flexibility and scalability. Organizations can tailor the software to meet their specific requirements, integrating it into their existing infrastructure seamlessly. Additionally, open-source solutions are often more cost-effective than proprietary alternatives, as they eliminate licensing fees and allow users to leverage a global community of developers for support and development.
In recent years, open-source video communication solutions have gained popularity due to their reliability, security, and privacy features. These solutions prioritize user data protection, offering end-to-end encryption and other security measures to safeguard sensitive information. As businesses and individuals increasingly rely on video communication for work, education, and social interactions, open-source solutions provide a reliable and accessible platform for connecting people around the world.
Primarily open source solutions can be divided into 2 categories. One is a ready solution with both frontend(UI) and backend ready to be deployed on the server and used. The downside of this is that the front end (UI) may not be suitable for your use case. A great example in this category is Jitsi. Jitsi is a ready to be used open source video conferencing solution with a pre-built UI with a scalable backend. The only issue is that we can use the default UI as an IFrame inside our solution but can’t modify it easily according to our use case. Also, it may not be a great Twilio video alternative as Twilio video is used to provide the APIs to build a custom video solution according to our exact needs.
Therefore let’s explore the second alternative,i.e. a media server-based solution that provides a set of APIs to build custom video conferencing/ Interactive live streaming solutions like Twilio video currently provides. Though there are a good number of open-source Twilio alternatives, we are going to mention the top 2 alternatives that can be worthy of replacing Twilio video APIs. One great example is the mediasoup-demo project which can be considered as a real Twilio video alternative. It has all the ingredients for building a production-grade video conferencing/ Interactive live streaming system. The only downside of this project is that it is a raw tech that has been built to demonstrate the capabilities of the mediasoup media server. Hence it lacks the polish of a production-grade video application. This can be considered as a great base/starting point on top of which a production-grade video conferencing / Interactive live streaming application can be built. Please note that the APIs provided by the mediasoup-demo project are not the same as Twilio and they need a separate integration effort than the existing Twilio implementation. Another very good project is liveKit, built using PION, the Go lang version of WebRTC. If you have a Go lang backend, then this project can be worth the consideration.
Open source Twilio Video Alternatives, Pros and Cons

- Quality Control: Open source projects may lack the same level of rigorous testing and quality control as commercial solutions, potentially leading to reliability issues.
- Legal Considerations: Open source licenses may have implications for proprietary use, requiring careful consideration of licensing terms and compliance.
Open Source Considerations, Building from Scratch vs. Using a Vendor
Building from Scratch:
Building from scratch can be considered an option if you have
- At least 3-5 Highly Skilled people in the core Audio/Video technologies like WebRTC, SIP, FFMPEG, GStreamer, WebSockets
- Peripheral skill sets like JavaScript, HTML, Android, iOS, etc. for building Web and mobile clients
- If you have at least 12 months and enough financial resources to maintain a team of 8-10 available. It may go to 18-24 months if your requirement is too complex and it needs a very specialized approach.
- You will get the benefits of the above-mentioned pros but also you need to deal with the above-mentioned cons on your own.
Using a Vendor:
Using a vendor is beneficial as well as recommended if
- You don’t have a team with the above-mentioned skill sets who can understand and modify an open-source package according to your use case.
- You don’t have at least 8 – 12 months available for implementing your use case using an open-source package.
- You would get the pros of open source as mentioned above without having to deal with many of the cons as mentioned above. The vendor would provide you with much-needed support, scalability, and quality control capabilities.
- The financial resources needed would be similar to building it from scratch with the difference that you would get the results faster with better predictability and control of the outcome.
Commercial Twilio Video Alternative:
Nothing much needs to be written about commercial alternatives for the Twilio video. As the header suggests, this category has commercial vendors who provide audio/video SDK software similar to Twilio. The SDKs may not be the exactly same but they do the job effectively i.e. providing audio/ video capabilities in your application without you having to go through the pain of building the audio/video SDK for yourself.
These are some of the providers of audio/Video SDKs that offer similar audio/video capabilities as Twilio.
There are many others as well who provide video/audio SDKs. Please google and you will find others.
Pros
- Faster time to market: If you are not sure about the prospect of the product or service and you wish to test your product or service really quick
- No need to maintain a team of audio/video experts
- Easy to start with a lesser amount of cost when utilization is low
Cons
- Cost becomes prohibitive as usage grows with time
- Complex to forecast monthly costs with pay-per-minute/user billing techniques
- Chance of getting stuck with a vendor with a huge switch cost,( Vendor lock-in)
- Lesser control over the actual media streams of your users
- The fear of if Twilio can decide to shut down the video service, then your current vendor may also decide to shut it down next year!
- Sometimes your video SDK provider may not be flexible enough to customize according to your requirements.
The simple formula to choose between using a commercial vendor vs not using a commercial vendor is below.
If the audio/video capabilities are mission-critical to your business for some reason and are deeply coupled to the core workflows of your business, then it’s best not to choose a commercial vendor. In this case, it is better to look for alternatives that would provide you with better control over the entire stack of your audio/video capability requirement.

Introduction
WebRTC has become a cornerstone for real-time communication in web applications, enabling seamless audio, video, and data streaming directly in the browser. However, when it comes to IoT and embedded devices, leveraging WebRTC in a browser may not be the most efficient option. This is where compiling LibWebRTC natively for ARM devices comes into play. By doing so, developers can create highly optimized applications that significantly reduce CPU usage, resulting in lower power consumption and improved performance—key factors for IoT and embedded systems.
When you compile LibWebRTC for ARM, especially in the context of IoT and embedded devices, you unlock the potential to run real-time communication applications natively on ARM processors. This approach offers several advantages over using WebRTC within a browser, such as reduced latency, better resource management, and enhanced performance. The result is a more stable and reliable communication experience, which is crucial for applications in resource-constrained environments like smart homes, industrial IoT, and other embedded systems.
WebRTC for Embedded: Steps to Compile LibWebRTC for ARM
Compiling LibWebRTC for ARM, particularly for IoT and embedded devices, requires a few detailed steps. The following guide will help you through the process:
1. Set Up the Build Environment
Start by preparing an Ubuntu environment, either directly on an ARM device or on an x86 machine if you plan to cross-compile for ARM. Ensure that all necessary dependencies, such as Python, Git, and the build-essential package, are installed.
sudo apt-get update
sudo apt-get install build-essential python git
2. Fetch the LibWebRTC Source Code
Clone the depot tools repository, which is essential for managing the source code of LibWebRTC.
git clone https://chromium.googlesource.com/chromium/tools/depot_tools.git
export PATH="$PATH:/path_to_depot_tools"
Fetch the LibWebRTC source code using the following commands:
fetch --nohooks webrtc
cd src
gclient sync
3. Explore Available GN Build Options
Before generating the GN build files, it’s beneficial to review all available build options. This step ensures that you configure your build optimally for your IoT or embedded ARM device.
gn args out/Default --list
This command lists all configurable GN build options, allowing you to tailor the build process to your specific needs.
4. Set Up GN Configuration
Generate GN build files tailored to the target architecture, either ARM32 or ARM64.
For ARM32:
gn gen out/arm32 --args='target_os="linux" target_cpu="arm" is_debug=false is_clang=true use_custom_libcxx=false'
For ARM64:
gn gen out/arm64 --args='target_os="linux" target_cpu="arm64" is_debug=false is_clang=true use_custom_libcxx=false'
Selecting the correct target_cpu (either arm for ARM32 or arm64 for ARM64) is crucial for optimizing the build for your IoT or embedded device.
5. Compile the Code
Once the GN configuration is set, you can proceed to compile the code using Ninja.
For ARM32:
ninja -C out/arm32
For ARM64:
ninja -C out/arm64
The compilation process may take some time, depending on your system’s hardware capabilities.
6. Deploy and Test
After successfully compiling LibWebRTC for ARM, deploy the binaries to your target IoT or embedded device. Comprehensive testing is essential to ensure that all functionalities are working correctly and that the performance benefits specific to your device are realized.
Note:
While compiling for ARM devices, one should use this option is_clang=truewhich is required to compile the neon flags available in the ARM architecture for video rendering acceleration. The default GCC in the Ubuntu-based Linux systems is not capable of compiling these flags and complains about neon flags. Therefore, it is advisable to use the clang already provided by the LibWebRTC to compile it rather than using the system’s default C++ compiler which is GCC.
Summary
Compiling LibWebRTC for ARM devices, particularly in the context of IoT and embedded systems, offers significant advantages over using browser-based WebRTC. Native compilation allows you to fine-tune applications to run efficiently on ARM processors, resulting in lower CPU usage, reduced power consumption, and enhanced performance. This is especially important for IoT and embedded devices where resources are limited, and efficiency is paramount.
For businesses operating in the IoT and embedded systems domain, optimizing WebRTC for ARM devices by compiling LibWebRTC natively opens up a world of possibilities. It enables the delivery of high-quality video calls, low-latency data streaming, and efficient resource usage—all critical factors for success in this field. Whether you’re developing applications for remote healthcare, smart home devices, or industrial automation, the ability to provide reliable, real-time communication on low-powered ARM CPUs is a game-changer that can drive innovation and efficiency in your solutions.
We recently built a C++ video application for ARM devices (both 32-bit and 64-bit) to work with our existing cloud video infrastructure. From our recent experience, we can say that it’s not an easy task and needs significant effort to compile & build a native C++ video application.

by admin | Nov 6, 2025 | Enterprise WebRTC, WebRTC
In today’s digital-first world, enterprises are increasingly looking to enhance their workflows with real-time video communication capabilities. Whether it’s for a cloud contact center, customer engagement, or internal collaboration, WebRTC (Web Real-Time Communication) has emerged as the backbone for building custom video calling, conferencing, and live streaming applications. However, building a production-ready, enterprise-grade custom real-Time audio/video solution using WebRTC is no small feat. It requires careful planning, technical expertise, and a clear understanding of business needs.
Here are the top five points enterprises should consider before embarking on the journey of building and integrating a custom WebRTC application:
1. Define Business Use Cases and User Experience Requirements
Before diving into development, it’s crucial to outline the specific business use cases and the user experience (UX) goals. Are you building a customer-facing video support solution, an internal collaboration tool, or a live streaming platform for events? Each use case has distinct requirements for latency, resolution, and feature sets such as screen sharing, recording, or chat integration. Additionally, consider:
- Target audience and their technical proficiency.
- Device compatibility (web, mobile, and native applications).
- Regulatory requirements, such as HIPAA for healthcare or GDPR for customer data privacy.
A well-defined scope not only ensures a smoother development process but also aligns the solution with your business goals.
2. Ensure Scalability and Reliability
For enterprise-grade applications, scalability and reliability are non-negotiable. Video calls with hundreds of participants or live streams with thousands of viewers demand robust infrastructure. When planning your architecture:
- Opt for distributed servers and load balancers to handle peak traffic.
- Implement mechanisms to recover from failures, such as session restoration.
- Ensure low-latency media streaming for real-time interaction if it is a critical requirement for your application with techniques like media server cascading.
WebRTC itself doesn’t offer a signaling protocol—you’ll need to design or integrate one to manage session initiation, participant connection, and message exchange. Using standards like WebSocket or MQTT can provide the required reliability for signaling.
3. Optimize for Network Conditions and Bandwidth Management
Unstable network conditions can severely degrade the user experience in a real-time application. Enterprises should prioritize:
- Adaptive bitrate streaming to dynamically adjust video quality based on network bandwidth.
- Packet loss recovery techniques such as forward error correction (FEC).
- Configuring TURN (Traversal Using Relays around NAT) and STUN (Session Traversal Utilities for NAT) servers to ensure seamless peer-to-peer connections, even behind firewalls.
Testing the application across various network scenarios, including low bandwidth and high latency, is essential to delivering a consistent experience.
4. Incorporate Advanced Security Features
Security is a critical concern for enterprises, especially in industries like healthcare, finance, and government. WebRTC encrypts media streams by default using DTLS-SRTP, but additional measures should be considered:
- Implementing end-to-end encryption for sensitive communications.
- Using secure signaling channels (e.g., HTTPS and WSS).
- Regular security audits and compliance with standards such as ISO 27001.
Additionally, access control mechanisms, like token-based authentication, can prevent unauthorized use and ensure that only authenticated users can access the system.
5. Plan for Long-Term Maintenance and Updates
Building a custom WebRTC solution is not a one-time investment. As technologies and user needs evolve, so must your application. Enterprises should:
- Set up continuous monitoring and analytics to track performance and usage.
- Regularly update the application to address security vulnerabilities and incorporate new WebRTC standards.
- Invest in skilled developers who understand the nuances of WebRTC and its ecosystem.
Moreover, ensure your solution can integrate with other enterprise systems, such as CRM, ERP, or cloud contact center platforms, to provide a seamless workflow.
Alternatives to Building a Enterprise-Grade Custom Real-Time Audio/Video Solutions
While building a custom WebRTC application offers complete control and customization, it can be resource-intensive and time-consuming. For enterprises that want to fast-track implementation or lack in-house expertise, leveraging commercially available programmable video SDK solutions is a viable alternative. Vendors like Samvyo.com provide enterprise-grade APIs and SDKs that enable businesses to integrate video conferencing, live streaming, and real-time communication into their workflows without starting from scratch.
These solutions come pre-built with essential features like:
- Scalable infrastructure to handle high traffic.
- Pre-configured security and compliance mechanisms.
- Advanced analytics and monitoring tools.
Using a programmable video SDK not only reduces development time but also ensures a production-ready, reliable solution that can be tailored to your specific business needs. By partnering with trusted providers, enterprises can focus on delivering value to their users rather than managing the complexities of WebRTC development.
Final Thoughts
Enterprises looking to integrate real-time video communication into their workflows have a strategic decision to make: build a custom solution or leverage a programmable video SDK. While custom development offers unparalleled flexibility, it demands significant investment in time, resources, and expertise. On the other hand, commercially available SDKs from providers like Samvyo.com offer a faster and more cost-effective path to integration, enabling enterprises to stay agile in a competitive market.
Ultimately, the choice depends on your organization’s priorities, resources, and long-term vision. Whether you opt for a custom-built WebRTC application or a ready-to-use SDK, the key is to align the solution with your business objectives and deliver a seamless, secure, and scalable user experience.

In today’s fast-paced business world, customers expect more from brands than just products or services—they want personalized, seamless, and immediate support. The evolution of customer support systems, particularly cloud contact centers, has played a pivotal role in meeting these demands. As businesses shift from traditional telephony-based systems to cloud solutions, they are unlocking a new realm of possibilities for customer engagement and satisfaction. In this blog, we’ll explore the growing importance of cloud contact centers, their benefits, and how integrating advanced features like video calling, CRM systems, and webinars can take customer support to new heights.
What is a Cloud Contact Center and How It Differs from Legacy Telephony-Based Contact Centers?
A cloud contact center is a virtual call center hosted on the internet rather than relying on physical hardware or traditional telephony infrastructure. This solution leverages cloud computing technology to route calls, manage interactions, and provide support without the need for complex on-site setups.
The key difference between cloud-based and legacy telephony contact centers lies in the underlying technology. Traditional telephony contact centers rely heavily on dedicated hardware, such as PBX (Private Branch Exchange) systems, and are often tied to a fixed office location. This limits scalability, flexibility, and the ability to adapt to new communication channels.
Cloud contact centers, on the other hand, operate in a virtual environment, enabling agents to work from anywhere. They support multiple communication channels—voice, chat, email, and social media—integrating seamlessly with a brand’s CRM and offering advanced analytics. This flexibility allows businesses to scale up or down quickly based on demand, and at a fraction of the cost of traditional systems.
Benefits of a Cloud Contact Center without IVR Over a Legacy Telephony/IVR-Based System
The shift from legacy telephony systems to cloud contact centers provides organizations with an array of benefits that directly impact both operational efficiency and customer satisfaction. Here’s a deeper look into the advantages of cloud contact centers:
- Scalability and Flexibility: Cloud contact centers are inherently scalable, enabling businesses to quickly expand or contract based on demand. Unlike traditional telephony systems, which often require complex upgrades and additional hardware, cloud solutions allow businesses to add new agents or services seamlessly. This scalability is crucial for handling seasonal surges in customer interactions or business growth.
- Cost Efficiency: Cloud solutions significantly reduce the costs associated with maintaining physical infrastructure, such as servers and on-premise PBX systems. Businesses can leverage subscription-based pricing models, which are cost-effective and eliminate upfront hardware investment. This financial flexibility allows companies to allocate resources toward customer experience enhancements and other strategic initiatives.
- Advanced Features and Integration: Cloud contact centers support advanced functionalities such as omnichannel communication, real-time analytics, and AI-powered automation, which are difficult or costly to implement in legacy systems. Features like predictive routing, speech recognition, and chatbots enable businesses to handle customer interactions with greater accuracy and efficiency, improving the overall customer experience.
- Enhanced Security: Cloud providers offer robust security protocols, including encryption, multi-factor authentication, and compliance with industry regulations (e.g., GDPR, HIPAA). These features ensure that customer data is protected with the highest standards, which can be a significant challenge for traditional telephony systems that often lack such integrated security measures.
Running Cloud Contact Centers with IVR Numbers/Systems: Emerging Challenges
While IVR (Interactive Voice Response) systems have been a cornerstone of traditional contact centers, their integration into cloud-based platforms introduces a set of challenges that can hinder the customer experience. These issues are becoming more apparent as customer expectations evolve:
- Customer Frustration: The complexity and impersonal nature of traditional IVR systems can leave customers frustrated. Navigating through long menus or encountering dead-ends often leads to negative experiences. Customers increasingly prefer to bypass these barriers with direct access to agents or support teams who can offer personalized assistance.
- Lack of Contextual Awareness: IVR systems typically rely on pre-programmed decision trees that can’t adapt to real-time customer contexts. When a customer calls in with a specific issue or query, IVRs often fail to understand the nuances of the problem, which results in a less efficient service and can lead to unnecessary transfers to human agents.
- Inefficiency in Complex Queries: IVRs are great for simple, routine tasks (e.g., checking account balances or tracking orders), but they become ineffective when customers face complex issues that require more nuanced support. In these cases, IVR-driven contact centers often see longer resolution times and increased customer dissatisfaction.
- Missed Opportunities for Personalization: With IVRs, customers are often treated like case numbers, rather than individuals. A lack of personalization in these systems means that brands miss the opportunity to engage customers in meaningful ways, leaving them feeling less valued.
Browser/Mobile App-Based Calling: A New Era of Customer Experience
The integration of browser and mobile app-based calling solutions is fundamentally transforming customer interactions in cloud contact centers. This shift not only removes the dependency on traditional telephony systems but also empowers businesses to offer more efficient, seamless, and engaging experiences:
