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
