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

OK well that's weird.. in the code base: git grep mark-dead-on-options-fail
=>nothing.

I found the other similar occurrence, unregister - it gets triggered in
src/mod/endpoints/mod_sofia/sofia.c , line 4769 in head.
} else if (sofia_test_pflag(profile, PFLAG_UNREG_OPTIONS_FAIL)

I think some code needs to be reworked there to trigger an event even if
the unregister flag isn't set.
I'll have more time tomorrow to take a look and see if I have any clue what
I'm doing.
