That's important to know. If they are sent by ser and dropped by the
NAT then it is possible that your NAT requires two-way traffic to keep
the bindings open. If they are not sent by SER then the contacts in
the user location database expired because the user agent had failed
to update them.
I can not state definitively at this point that the udp ping packets are
being sent by ser and getting dropped at the NAT router, but I am pretty
sure this is what happening. I'm currently waiting to get access to the
nat router in question so I can verify this.
I have however had the same problem with two different brand nat routers
(D-Link and cisco).
What re-register time are people using (Successfully and other) on their
UAs in conjunction with rtpproxy (or even mediaproxy)?
