[OpenSIPS-Users] Linphone and OpenSIPS over TCP

[Bogdan-Andrei Iancu]

Hi,

I strongly suggest to look into the opensips logs and see what opensips 
try to do with the call. Based on your saying (that you see a timeout), 
I suspect your OpenSIPS tries to deliver the call over TCP to a 
destination which does not listen on TCP.
If you do not know hoe to interpret the logs, run opensips in debug=4 
mode, upload the logs corresponding the INVITE execution and provide the 
link.
