Hello
I have a problem when two clients (one using UDP and one using TCP) connect
to SER (version 0.8.13-dev-23). My scenario is more or less like this:
TCP Client <----> SER <----> UDP Client
There are no NATs or Firewalls in scene.
I want to reuse the TCP connection of the TCP Client for the whole SIP
signalling, so I have added the command force_tcp_alias(); to ser.cfg and
changed tcp_conn.h as advised in
http://lists.iptel.org/pipermail/serusers/2004-May/008262.html.
The TCP Client starts the call with an INVITE and everything works
correctly. However, when the UDP Client tries to send a MESSAGE, SER doesn't
route the MESSAGE through the TCP connection (it sends it over UDP with the
TCP port included in TCP Clients Contact!).
Can anyone tell me what is misconfigured?
A quick guess: the UDP client doesn't copy the proto parameter from the
TCP client Contact: into the request uri.
If this is not the case, please send some packet dumps (tcpdump -w file
or ngrep).
