Hello!
When a call starts I would like OpenSER to ping (by sending OPTIONS or
INFO request) both UAC´s just to know if they are still there or for
some reason they crashed or lost connectivity. In case they don’t
response, the call should be finished. What is the best way to do this?
what you need requires a back-to-back user agent, or at leas a call
stateful proxy.
There is the option of using session timer module (sst) if you know that
the devices support the session timer extension -- most of the gateways
support it.
http://www.kamailio.org/docs/modules/1.4.x/sst.html
Otherwise, with some development in top of dialog module you can get the
functionality -- working with kamailio/openser as a call stateful proxy.
Cheers,
Daniel
