asterisk users - Nov 2005 - how to originate a call and capture it's DIALSTATUS

Hello,

I've been trying to originate calls and capture the DIALSTAUS via the
manager API. The problem seems that the API doesn't expose enough data to
make a decision of what exactly happened to the call. It results in
something like this:

Action: Originate
Channel: IAX2/switch/1<number>
MaxRetries: 0
WaitTime: 2
Context: reminder
Extension: s
Priority: 1
Callerid: "Reminder" <555-555-5555>

Event: Hangup
Privilege: call,all
Channel: IAX2/switch-3
Uniqueid: 1132271784.42
Cause: 0
Cause-txt: Unknown

this is far from detailed. Is there a way to extract the actual DIALSTATUS
such as ANSWER,BUSY,CONGESION, etc? The Cause doesn't seem to return 0 when
the call is terminted thru IAX2 or SIP. It seems that it works on ZAP only.

There are two things you could try.

1. Add "Async: yes" to the Originate action, and then watch for the
OriginateSuccess and OriginateFailure events.

2. If that doesn't reveal the wanted information, then I would consider
it a bug, but you could workaround it by using a Local channel:

[outgoing]
exten => _X.,1,Dial(IAX2/switch/1${EXTEN})
exten => _X.,2,UserEvent(Fail|Dialstatus: ${DIALSTATUS})

Then in your Originate action use Channel: Local/<number>@outgoing
and look for the UserEventFail event.

Hope this helps!
Cheers
Tony
