Hello,
what would be relevant here is seeing the INVITE request sent to
10.14.0.1:5060 -- paste it to the mailing list discussion. That is going
to be used to generate 487, and the Via stack from it should be used there.
Cheers,
Daniel

Hello,
We’re testing kamailio 4.3.4 with two kamailio’s communicating with
each other. One of them is a gateway with rtpengine at the carrier
side, the other is a basic sip router.
When calling a destination and cancelling the INVITE a 487 is received
from the carrier and directly ACK’d by the first kamailio and in turn
is forwarded to the second.
But the 487 response received by the 2^nd kamailio doesn’t have a Via
header which results in kamailio printing the error: receive_msg(): no
via found in reply.
Any ideas why the forwarded 487 doesn’t contain a Via header and how
to fix this?
Note: IP’s are changed.
