[SR-Users] proxy is not forwarding 180 ringing reply

[Juha Heinanen]

i compared debug of failing 180 reply to working one and i don't see any
other difference except in working one reply gets relayed:

...
Oct 23 18:07:43 rautu /usr/sbin/sip-proxy[8738]: DEBUG: tm [t_lookup.c:1140]: t_check_msg(): DEBUG: t_check_msg: msg id=11 global id=11 T end=0xb425e168

Oct 23 18:07:43 rautu /usr/sbin/sip-proxy[8738]: INFO: Received reply

...

in failing one it does not happen and things are cleaned up:

...
Oct 23 17:40:51 rautu /usr/sbin/sip-proxy[8730]: DEBUG: tm [t_lookup.c:1140]: t_check_msg(): DEBUG: t_check_msg: msg id=5 global id=5 T end=0xb4256d88

Oct 23 17:40:51 rautu /usr/sbin/sip-proxy[8730]: INFO: Received reply

[usr_avp.c:644]: destroy_avp_list(): DEBUG:destroy_avp_list: destroying
list (nil)
...

in both cases the reply code is the same and debug shows that the status
of the reply is the same.

why reply is not relayed in the failing test?  why does kamailio think
that it should not relay the reply?
