[Freeswitch-users] SRTP breaks my TLS session

[Emrah]

Thanks for this. 

This isn’t just a yealink thing. I’ve encountered sporadic issues with soft phones and other desk phones as well.

I didn’t use the PCap capture feature because I had assumed it would give me a bunch of TLS packets. I’ll test that and revert back.

How can we explain that I have more calls failing if I register multiple accounts?
