[asterisk-users] Why CONGESTION not *NOANSWER** ?

Wed Dec 21 07:13:36 CST 2011

"  -- Got SIP response 480 "Temporarily Unavailable" back from 10.10.11.203"  this is why you are getting congestion instead of NOANSWER.   Fix that and add a timeout to your dial and it should work.

Subject: [asterisk-users] Why **CONGESTION** not *****NOANSWER****** ?

Hi List,

I have a DID number which is routed to my production server. Problem is that when I dial that DID number from my production number then it's gives DIALSTATUS to CONGESTION if I don't pick the calls. As per the asterisk it should reply NO ANSWER.

extensions.conf :-

exten => 08723310476,1,Dial(SIP/2218)
        same => n,NoOp(**${DIALSTATUS}**)
        same => n,ExecIf($['${DIALSTATUS}'='CHANUNAVAIL']?NoOp(Channel unavailable. On SIP, peer may not be registered.))
        same => n,ExecIf($['${DIALSTATUS}'='BUSY']?noop(Busy signal. The dial command reached its number but the number is busy.))
        same => n,ExecIf($['${DIALSTATUS}'='ANSWER']?noop(Call is answered. A successful dial. The caller reached the callee.))
        same => n,ExecIf($['${DIALSTATUS}'='NOANSWER']?noop(No answer. The dial command reached its number, the number rang for too long, then the dial timed out.))
        same => n,ExecIf($['${DIALSTATUS}'='CANCEL']?noop(Call is cancelled. The dial command reached its number but the caller hung up before the callee picked up.))
        same => n,ExecIf($['${DIALSTATUS}'='CONGESTION']?noop(Congestion. This status is usually a sign that the dialled number is not recognised.))
        same => n,ExecIf($['${DIALSTATUS}'='DONTCALL']?noop(Privacy mode, callee rejected the call))
        same => n,ExecIf($['${DIALSTATUS}'='TORTURE']?noop(Privacy mode, callee chose to send caller to torture menu))
        same => n,ExecIf($['${DIALSTATUS}'='INVALIDARGS']?noop(Error parsing Dial command arguments))
        same => n,wait(9)

        same => n,ExecIf($['${DIALSTATUS}'='INVALIDARGS']?noop(Error parsing Dial command arguments))
        same => n,Hangup()

exten => h,1,NoOp()
        same => n,NoOp(********${HANGUPCAUSE}*********)
        same => n,NoOP(bye Virendra)
