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.
