I have been working on a project which requires Asterisk as SIP proxy. I am able to register, call and recieve calls with the my setup of asterisk.
Only problem is that Asterisk quits intermittently without any crash dumps or segregation fault nothing!. Also I found that as there's not any reachable users it quits. On restarting i see messages for last qualify 0 for user last reached.
Pretty much stuck on this issue, any help would be much appreciated.!
Asterisk is not PROXY, it is pbx.
For proxy(load over 1k calls or CPS over 80) please use kamailio.
You have enable core dump and compile asterisk with debug flags to do debugging.
You also may consider change pjsip to chan_sip or via versa.
