Hi All,

I'm seeing random errors in my Kamailio 3.0.2 log:

ERROR: tm [tm.c:1300]: ERROR: w_t_relay_to: t_relay_to failed ERROR: tm [t_fwd.c:1379]: ERROR: t_forward_nonack: no branches for forwarding

After going blind staring at wireshark, I can consistently reproduce this error by initiating a call, then after about a second ro two, quickly hanging up. So here is my setup:

SIP Phone><Asterisk><Kamailio><SIP Service Provider

I see all transaction messages flowing properly through all nodes and I don't get any hung channels, all call legs release properly.

I'm guessing I need a special [route] in Kamailio to handle 487 request so they look normal and not issue an error?

Kamailio is forwarding the 487 messages ok, so why do I get a t_relay error? What info would be helpful to diagnose the errors?

Any insight would be appreciated.

Thanks.

JR

You need to use xlog to see where the problem is. Each time I've seen that is because the config file was missing that target.

Please log the issue a little bit more. $du values specially.
