<tt>Hi Ryan,<br>
<br>
To answer your question on t_realy() and how it decides on the
sending interface - normally OpenSIPS tried to preserve the
interface (outbound <= inbound) if the protocol and routing
allows it (if you do not explicitly change proto or interface). If
preserving is not possible (incoming via UDP, but destination is
TCP), it will use the first listener matching the needed outgoing
protocol. <br>
Definitely the SIP FROM is not involved at all in this logic !!<br>
<br>

<p class="MsoNormal">I’m hoping someone can direct me to some
documentation or help me out. I’m trying to send an invite to
something outside my domain. Everything seems to work but no
packets come back to opensips. I see the packets on the wire
coming to the machine but it looks like the tcp port that was
used to send stuff out isn’t there anymore. A colleage found
this gem in the log: “<span style="color:black">proto_tcp_send:
Successfully connected from interface 209.197.207.36:5060 to
209.197.207.36:5060” thinking that maybe the tcp connection
was opened by mistake with the local side not set correctly.<o:p></o:p></span></p>

<p class="MsoNormal"><span style="color:black">My question is
when t_relay is called how does it know the from address? I
printed out my from domain $fd and it is using my internal
domain, which works out to be a 192.168 address. The address
listed above is from a successfully DNS look up on the
request URI domain and it works out to be the above address.<o:p></o:p></span></p>
