Hello all,
We're having an issue with Kamailio not processing an ACK and hope someone
can help. A PCAP shows that Kamailio is receiving the ACK, and we believe
these log messages are directly related to it:
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm [ut.h:279]:
uri2dst2(): ERROR: uri2dst: bad transport for sips uri: 1
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: tm [t_fwd.c:1777]:
t_forward_nonack(): ERROR: t_forward_nonack: failure to add branches
Feb 21 10:54:01 hostname /sbin/kamailio[15854]: ERROR: sl [sl_funcs.c:387]:
sl_reply_error(): ERROR: sl_reply_error used: Unresolvable destination
(478/SL)
The ACK is as follows. It's from telephone 111111 which is using TLS, which
Kamailio listens for on port 5061.
Does anyone know which URI has the bad transport as per the error above?
Might it be the From URI "sips:111111@es8.example.com" because it doesn't
specify port 5061?
Thank you in advance.
