Cases when WebRTC (Web Real-Time Communication) does not work

1. Unsupported Browsers: One of the primary limitations of WebRTC is its browser support. While major browsers such as Google Chrome, Mozilla Firefox, and Opera have built-in support for WebRTC, other browsers like Internet Explorer and Safari have limited or no support. This means that if a user is using an unsupported browser, WebRTC will not work for them.
2. Firewall and NAT Traversal: WebRTC relies on peer-to-peer communication, which can be hindered by firewalls and network address translation (NAT). In some cases, firewalls may block the required ports or protocols necessary for WebRTC to establish a direct connection between peers. Similarly, NAT can pose challenges in establishing direct connections, especially when both peers are behind symmetric NATs. Consequently, WebRTC may not function properly if these network configurations are present.
3. Network Limitations: WebRTC requires a stable and reliable network connection to function optimally. If a user has a poor internet connection or is experiencing network congestion, it can negatively impact the quality and reliability of WebRTC communication. Factors such as high latency, packet loss, or limited bandwidth can lead to dropped calls, audio/video quality degradation, or even complete failure of WebRTC.
4. Security and Privacy Concerns: While WebRTC offers secure communication through encryption protocols, there are still potential security and privacy risks. In certain cases, users may have concerns about sharing their IP addresses or exposing their real-time communication to unauthorized parties. Consequently, some users may choose to disable WebRTC or use additional tools to mitigate these risks, resulting in WebRTC not functioning as intended.
5. Hardware and Device Limitations: WebRTC heavily relies on device capabilities, especially for real-time audio and video processing. Older or low-end devices may not have sufficient processing power or hardware acceleration capabilities to handle the demands of WebRTC. This can lead to performance issues, including audio/video lag, choppy playback, or even crashes. Additionally, if a user’s device lacks a microphone or camera, WebRTC will not be able to establish audio or video communication.
