[OpenSIPS-Users] from address in the t_relay

Hi list,

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: "proto_tcp_send: Successfully connected from interface to" thinking that maybe the tcp connection was opened by mistake with the local side not set correctly.

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.
