How to get originate call duration in Asterisk?

Question

Asterisk

Hello.
I implemented an outgoing call on the site using phpagi through the Originate method:

$actionID = md5($input_phone.$manager_phone.time()); // Уникальный ID
if ($asm->connect()) {
  $call = $asm->send_request('Originate',
        array(
        'Channel'=>"Local/".$manager_phone."@from-internal",
        'Context'=>'from-internal',
        'Exten'=>$input_phone,
        'Priority'=>'1',
        'Callerid'=>"%ID оператора%",
        'Async' => "yes",
        'ActionID' =>  $actionID
        ));
  $asm->disconnect();
}

Everything works - calls go. There was a need to get the duration of these calls. And this is where things got weird. I found the CoreShowChannels method in the documentation, to which you pass the ActionID and it allegedly returns the duration of the call. When I call this method while connecting via telnet, the results are:

Response: Success
ActionID: c78d1d8c43e9b14a
EventList: start
Message: Channels will follow

Event: CoreShowChannel
Duration: 00:16:57
...

However, when I make the same request via PHP, I only get the top part of the Array in response ( [Response] => Success [ActionID] => c78d1d8c43e9b14a [EventList] => start [Message] => Channels will follow )
Maybe after call send_request CoreShowChannels need to do some additional stuff to get the results of Events? Can anyone at least point me in the right direction?
Thanks in advance!

Answer 1

Catch Event: OriginateResponse

Action: login
Username: test
Secret: test
Events: on

Action: Originate
Channel: SIP/331
Application: Hangup
ActionID: adaff
Async: yes

Event: OriginateResponse
Privilege: call,all
ActionID: adaff
Response: Success
Channel: SIP/331-000003e0
Context: 
Exten: 
Reason: 4
Uniqueid: 1441039425.992
CallerIDNum: <unknown>
CallerIDName: <unknown>

It is sent when the channel specified in Channel responds
.
But most importantly, you get a Uniqueid, by which you can further connect with subsequent Events.
