[Freeswitch-users] Monitoring Phone Endpoint Deregistration/Losing Connection

[Michael Jerris]

If you waited for it to expire, it would have been re-registered, then you unplugged it, not giving it a chance to unregister?

First thing I'd suggest is that you get FS running on a laptop or some old sandbox system and put just a single phone on it so that you can more easily focus on the relevant events. Second, if you just unplug a phone then there's no way it can send an "unregister" REGISTER message. (I believe that an "unregister" is really just a REGISTER with expires time of zero.)
