[OpenSIPS-Users] iOS 15 WebRTC

[Callum Guy]

Hi All,

I'm wondering if anyone in the community has encountered the iOS 15 WebRTC
bug as reported here:

https://www.wowza.com/community/t/ios-15-webrtc-problem/93868/4
https://developer.apple.com/forums/thread/689293

The bug causes INVITES to fail to be digested by opensips with a log
message as shown below:

opensips[217976]: ERROR:proto_wss:ws_process: Made 4 read attempts but
message is not complete yet - closing connection

Worth noting is that REGISTER messages still arrive so as mentioned in the
article is does appear related to fragmentation of the messages being sent
through, perhaps failing to conclude this for reassembly but I can't make
sense of the network trace.

My client device is using SIP.js and I can confirm that it continues to
work on Android and other iOS versions. I'm currently running opensips
3.0.5 and would happily upgrade to the latest version if there was anything
worth trying or wolfssl has any potential to resolve this issue!

Thanks,

Callum
