A text sip trace of the whole thing would help in figure out what exactly is going on. On Jul 18, 2014, at 11:28 AM, Trever L. Adams <trever@middleearth.sapphiresunday.org> wrote:
https://wiki.freeswitch.org/wiki/SIP_TLS#Limitations_of_the_Freeswitch_TLS.2... mentions that lib_sofia and FreeSWITCH uses two ports, by default, for TLS (client -> server for registration and client to server signaling, and server->client for NOTIFYs, etc.).
In one setup, I need to get CSIPSIMPLE (an Android SIP client with ZRTP support) working. It appears to accept the server->client connections, but will not ring, etc. for incoming calls. This does seem to be a bug there, and it only exists with TLS (not tcp/udp).
So, is it possible to force FreeSWITCH/Sofia to use the client->server connection for server->client NOTIFYs?
Thank you, Trever
