[SR-Users] Kamailio 4.3.4: receive_msg(): no via found in reply

Hello,

the problem is that the device you interconnect with (Server: sbc_5) is
not sending all the Via headers from INVITE in the 487 -- it is only one
Via:

# U 10.0.0.1:5060 -> 10.14.0.1:5060

SIP/2.0 487 Request Cancelled.
Via: SIP/2.0/UDP
10.14.0.1;branch=z9hG4bK3c3b.a6603e0f92db305f775f8bf1d95dc7d9.0.

Call-ID: 78100ZGIyZGM2ZTY4ODM4YWZlZGFjNTBjMDZmYjQzMzBkOGI.
Contact: <sip:10.0.0.1:5060>.

Notice the 100 trying Via stack:

# U 10.0.0.1:5060 -> 10.14.0.1:5060

SIP/2.0 100 Trying.
Via: SIP/2.0/UDP

Server: sbc_5.

My guess that the sbc_5 is so poor implemented that it takes the Via
from last request, which is CANCEL, but CANCEL is a hop-by-hop request
in this case. If my guess is confirmed, the implementation of sbc_5 is
really far away from RFC3261, something that I haven't probably seen
since 2002/3.

To test, you can try to use forward() for CANCEL instead of t_relay().
But you need to know where to send it -- same address as for INVITE --
you can hardcode some values in config for sake of simplicity to test. A
proper workaround can be built using htable module to store where the
invite was sent, using call-id as a key.

Cheers,
Daniel
