[OpenSER-Users] How to detect lack of response to SIP nat ping?

[Mike Fedyk]

Hi,

I'm trying to come up with some code in openser that will log when a SIP UA
does not respond to a SIP NAT ping.  The best I can think of so far is using
the sip timers module, but it is based on the INVITE method instead OPTIONS
that is the nat ping default.

Does anyone have any ideas that can point me in the right direction?

Thanks,

Mike
