Hi,
I am using pjsua to connect from a NAT-ed network to a my sip proxy
(openser) which is doing everything i need to have sip-over-nat
without the need to tun the client. (it will keep the open SIP
connection by pinging it and use mediaproxy from ag-projects to
handle the RTP that could be coming from another port that
announced in the SDP).
It work very well with SNOM, AASTRA, etc, but for some reason pjsua
will refuse re-registering.
I suppose it's because it can see in the REGISTER's reponse that
his IP in contact field has changed. But i don't understand why.
Since we are already handling everything NAT need at the server-
side, pjsua shouldn't refuse to register again.
Here is the SIP trace of my pjsua, as you can see at the end, it
show ("expire=-1") which is the problem.
If someone could tell me why pjsua has this behaviour, and, how to
tun it for it to ignore this. Would be great.
Thanks,
Nicolas
p.s. : as you can see i am on LAN with ip 172.16.2.14 and
contacting a WAN ip, here masked as being "registrar.org".
