TwiML™ Voice: <Queue>
<Queue> noun specifies a queue to dial. When dialing a queue, the caller will be connected with the first enqueued call in the specified queue. If the queue is empty, Dial will wait until the next person joins the queue or until the <Dial> timeout duration is reached. If the queue does not exist, Dial will post an error status to its action URL.
<Queue> noun supports the following attributes that modify its behavior:
|Attribute Name||Allowed Values||Default Value|
|url||relative or absolute URL||none|
url attribute takes an absolute or relative URL as a value. The url points to a Twiml document that
will be executed on the queued caller's end before the two parties are connected. This is typically used
to be able to notify the queued caller that he or she is about to be connected to an agent or that the call may be recorded.
The allowed verbs in this TwiML document are Play, Say, Pause and Redirect.
Twilio will pass the following parameters in addition to the standard TwiML Voice request parameters with its request to the value of the 'url' attribute:
|QueueSid||The SID of the queue.|
|CallSid||The CallSid of the dequeued call.|
|QueueTime||The time the call spent in the queue in seconds.|
|DequeingCallSid||The CallSid of the call dequeuing the caller.|
method attribute takes the value 'GET' or 'POST'. This tells Twilio
whether to request the
url above via HTTP GET or POST. This attribute
is modeled after the HTML form
method attribute. 'POST' is the default value.
If a call was enqueued with a TaskRouter Workflow Sid, you may specify a Reservation Sid in order to bridge this call to the enqueued caller. Once the call has been successfully bridged the pending Reservation will be marked as 'accepted'.
If a call is bridged using the 'reservationSid' attribute, you may specify an optional
postWorkActivitySid value to indicate the what activity state that the Worker should be moved to after the call completes.
Example 1: Dialing a queue
In this example, the caller wants to dequeue a call from the 'support' queue. Before connecting, the following TwiML might be executed:
And the 'about_to_connect.xml" TwiML document which will be played to the caller waiting in the queue before connecting might look something like this:
