[Asterisk-bsd] hangup detection

[Jeff LaCoursiere]

Hello all,

Just for posterity I thought I would post what I ended up with... we
decided that rather than hangup the line, we will send the call to the
operator after three invalids or one timeout.  I discovered how amazingly
anal asterisk is about spacing in numeric expressions!  So here it is:

;
; Southland's main welcome menu
;
[main]
exten => s,1,Answer
exten => s,2,DigitTimeout,3
exten => s,3,ResponseTimeout,3
exten => s,4,setvar(RETRIES=0)
exten => s,5,BackGround(sgvi-welcome)

[timeout]
exten => t,1,Playback(sgvi-tooper)
exten => t,2,Macro(stdexten,220,SIP/dot) ; timeout goes to operator
exten => i,1,setvar(RETRIES=$[${RETRIES} + 1])
exten => i,2,gotoif($[${RETRIES} > 2]?20)
exten => i,3,Playback(invalid)
exten => i,4,Goto(s,5)
exten => i,20,Playback(sgvi-tooper)
exten => i,21,Macro(stdexten,220,SIP/dot) ; 3 tries goes to operator

I still think I have some kind of problem detecting hangups on the FXO
ports.  Could this be my choice of kewlstart signalling?  Should I play
with loop/ground start?  I expect what may happen now is that we will get
blank voicemail messages in the operator mailbox :)

Thanks,
