------------------------------------------

First of all, wow, thanks for such a fast response!

Answers to questions in above comment:

1. Nope, nothing was changed from when it was working to when it started breaking. I literally went to sleep with it working and the next day it was not working.
2. Checking on this, will post what I find
3. Currently testing with Snom 370 to outside line, and Snom 370 to internal line on Blink Lite. It also failed on Snom 370 to Snom 370. Here are the dialplan details:
exten => {redacted sip trunk auth name},1,Answer()
exten => {redacted sip trunk auth name},n,Wait(2)
exten => {redacted sip trunk auth name},n,Background(/usr/share/asterisk/customsounds/aaGreeting)
exten => {redacted sip trunk auth name},n,WaitExten()
exten => {redacted sip trunk auth name},n,Hangup()

exten => 8,1,Directory
exten => 8,n,Hangup 

exten => *98,1,VoiceMailMain
exten => *98,n,Hangup 


exten => _X.,1,Dial(SIP/${EXTEN},20)
exten => _X.,n,Voicemail(${EXTEN},u)
exten => _X.,n,Hangup()

exten => _NXXXXXXXXX,1,Dial(SIP/trunk1/${EXTEN})

exten => _1NXXXXXXXXX,1,Dial(SIP/trunk1/${EXTEN})
exten => _1NXXXXXXXXX,n,Congestion()

exten => _+NXXXXXXXXX,1,Dial(SIP/trunk1/${EXTEN})
exten => _+NXXXXXXXXX,n,Congestion()
exten => _+NXXXXXXXXX,n,Hangup()

exten => _+1NXXXXXXXXX,1,Dial(SIP/trunk1/${EXTEN})
exten => _+1NXXXXXXXXX,n,Congestion()
exten => _+1NXXXXXXXXX,n,Hangup()


4. Haven't done this before so I will research how to do it and then post the results. If there is an example on a forum or a preferred way you have of me doing this, let me know and I'll be happy to follow that.

> Installed asterisk from source and it worked perfectly for days, then today it suddenly stopped working. I can start the Asterisk service and as soon as a call is attempted it crashes / segfaults and does a core dump if run with that option to do a core dump.
