[Asterisk-Users] manager api: how to handle failed calls

[Luca Casavola]

Hello Nicolas, first of all I want to thank you. You are the first guy 
give me an answer. I already posted this issue two times but nobody was 
interested in it.
I tried your sugggestion but it doesn't work. In the mean time I 
upgraded to v1.0.2 but things remain the same or even worse ( I have in 
the log a new channel name OutgoingSpoolFailed but the behaviour is the 
same).
Any way perhaps I found a solution and I would like to ask what do you 
think about it:
This is the request:
/bin/echo "Action: Originate";\
/bin/echo "Channel: Local/XXXXX at chiamamezzi3";\
/bin/echo "Variable: 
callid=123456|number=XXXXX|url=pippo|menuid=FOP|redirectnum=YYYYY";\
/bin/echo "Context: chiamamezzi3";\
/bin/echo "Exten: s";\
/bin/echo "Priority: 1";\
/bin/echo "Callerid: Asterisk Automatic Wardial";\
/bin/echo "Timeout: 10000";\
/bin/echo "Async: True";\  ** this is important otherwise fail extension 
doesn't work **
/bin/echo "ActionId: 10";\

This is the context
[chiamamezzi3]
exten => _.X,1,Dial(ZAP/g1/${EXTEN})
exten => _.X,2,NoOp( _.X  DIALSTATUS is ${DIALSTATUS}, number is ${number} )
exten => _.X,3,SetGlobalVar(status=${DIALSTATUS})
exten => s,1,Wait,1
exten => s,2,Answer
exten => s,3,DigitTimeout,5
exten => s,4,ResponseTimeout,10
exten => s,5,system(/prd/asterisk/log.sh "Variabili: [menuid=${menuid}] 
[number=${number}] [redirectnum=${redirectnum}] [url=${url}] 
[callid=${callid}]")
exten => s,6,Goto(chiamamezzi-${menuid},s,1)
exten => t,1,Goto(noanswer,s,1)
exten => failed,1,NoOp( failed  DIALSTATUS is ${status} number is ${number})
exten => failed,2,Hangup()
exten => h,1,Hangup()


As I told you, If the call is ok dialplan goes on s, 1
If the call fails I proceed on _.X,2 and 3 and I need to set a 
globalvariable to let to handle it  in the failed extension.
It works but I don't know if it could work on multi request environment 
. It would be much better to use a channel variable or even better, to 
have DIALSTATUS directly available .
