Hey Steve,

Can provide us a snippet of code on how you are populating the $ru and making invoking the relay?

Hello,

I am still struggling with getting TCP relay to work. Kamailio is now trying to send TCP but it is using the incorrect port. Kamailio is relaying to Asterisk on xx.xx.xx.xx:some-large-port but Asterisk is listening on xx.xx.xx.xx:5060. I’m not sure why this is happening. I would appreciate any help.

What is the full and exact RURI of the request immediately prior to relay, and also the value of $du?

Can you xlog() both $du and $ru prior to t_relay() and tell us what those values are?

Thanks,
