Hello, i'm using AMI Originate action (with async=true) to send
outgoing calls to a SIP trunk (using asterisk-java library to connect
to AMI).
The problem is that in case of failed originate, OriginateResponse
event is returning only the reason code which is sometimes not
sufficient to determine the real cause of failure. Also, there's no
way to link between the channel that was trying to dial and failed and
the original Originate request, because OriginateResponse is issued
only after the failed channel was hang up. Only successful
OriginateResponse will contain the unique id of the established channel.
Is there any way that my AMI application can get the original SIP
response of the failed Originate action?
I'm using Asterisk 1.8.22 and slightly tweaked asterisk-java
(https://blogs.reucon.com/asterisk-java/) 1.0.0.
You could dial a local channel instead and have that then go on and dial
the destination. You will then be able to retrieve the sip response
using something like :-
[localdial]
exten => _X.,1,Set(ddi=${CUT(EXTEN,,1)})
exten => _X.,n,Set(carrier=${CUT(EXTEN,,2)})
exten => _X.,n,Set(dialtime=${EPOCH})
exten => _X.,n,Set(_MASTERCHANNEL=${CHANNEL})
exten => _X.,n,Dial(SIP/${ddi}@${carrier})
exten =>
_X.,n,Set(SIPcause=${MASTER_CHANNEL(HASH(SIP_CAUSE,${CDR(dstchannel)}))}, Responsetime=$[${EPOCH}-${dialtime}])
exten => _X.,n,Set(SIPcode=${CUT(SIPcause," ",2)})
However you will need to set "storesipcause=yes" in your sip.conf for
this to work. It is known to have a performance hit.
A better way would be to upgrade Asterisk and use hangup handlers. The
documentation on how to do this in Asterisk 11 is poor and often wrong.
I have written a blog about how we set it up as we use the feature all
the time.
