[OpenSIPS-Users] OpenSips and WebRTC ERRORS

Tue Apr 4 05:57:42 EDT 2017

Hi Dragomir,

Those errors translate into a failed attempt to connect via TCP (for WSS 
protocol) to the needed SIP destination. OR, when you do t_relay() in 
the script, you have a SIP destination that does not accept the TCP 
connections from OpenSIPS. Are you sure that the destination/callee 
party is able to accept incoming TCP connections ?

Best regards,
