Hello all,
Thank you for your all your answers
I checked the headers and I 've seen several things:
1/ In the Invite I see :
sip:test@KAMAILIO_SERVER_IP
In the reinvite i see:
sip:remote_endpoint
via Kamailio IP address
2/ In the call flow everything is going well until the ack.
At the beginning of the reinvite, the route is well known
The caller send the ack to Kamailio but Kamailio is unable to forward it to the remote
endpoint.
Checking the headers, I see that in the ACK, the route is not present anymore.
Is it possible to force the route in Kamailio directly ?
I have the call flow but I cannot send image here.
although it should not be done according to the specs, maybe the end
point implementation refreshes the record-route set with the re-INVITE.
Try by adding record_route() when processing the re-INVITE (inside the
route[WITHINDLG] if you use the structure of the default kamailio.cfg).
See if it helps.
Cheers,
Daniel
