If this call was an incoming call forwarded from another number, the forwarding phone number (depends on carrier supporting forwarding). Empty otherwise.

CallerName

If this call was an incoming call, the caller’s name. Empty otherwise.

Uri

The URI for this account, relative to https://$DOMAIN/restcomm/2012-04-24/.

Call Duration

The call duration shall be equal to the difference between the startTime and endTime timestamps, rounded up using a ceiling function. For example, if the delta between start/end timestamps is 10.1 seconds, then the call duration is 11 seconds.

When the application processes a Dial verb, the dial ringing time will NOT be taken into account. This measure prevents overcharging in situations such as when the RCML application consists of a single Dial verb, for example.

Get call details

HTTP GET. Returns the representation of a Call resource, including the properties above.

Call List Resource URI

/2012-04-24/Accounts/{AccountSid}/Calls

A comma separated list of events on which we are interested to get a callback on. Possible values are initiated, ringing, answered, completed. Default none

StatusCallback

URL to receive the callback events at. Default none

StatusCallbackMethod

GET, POST. Default POST

Timeout

The number of seconds that CPaaS should allow the phone to ring before assuming there is no answer. The default is 60 seconds.

StatusCallbackEvent

When creating a Call using the Calls API, an outbound call is initiated. The call transitions from the initiated state to the ringing state when the phone starts ringing. It transitions to the answered state when the call is picked up, and finally to the completed state when the call is over. With StatusCallbackEvent, you can subscribe to receive webhooks for the different call progress events: initiated, ringing, answered, or completed for a given call.

The StatusCallbackEvent attribute allows you to specify which events CPaaS should webhook on. To specify multiple events separate them with a comma like this: initiated,ringing,answered,completed. If a StatusCallback is provided and no status callback events are specified the completed event will be sent by default.

Event Description

Event	Description
initiated	The `initiated` event is fired when CPaaS starts dialing the call.
ringing	The `ringing` event is fired when the call starts ringing.
answered	The `answered` event is fired when the call is answered.
completed	The `completed` event is fired when the call is completed regardless of the termination status: `busy`, `canceled`, `completed`, `failed`, or `no-answer`. If no `StatusCallbackEvent` is specified, `completed` will be fired by default.

initiated

The initiated event is fired when CPaaS starts dialing the call.

ringing

The ringing event is fired when the call starts ringing.

answered

The answered event is fired when the call is answered.

completed

The completed event is fired when the call is completed regardless of the termination status: busy, canceled, completed, failed, or no-answer. If no StatusCallbackEvent is specified, completed will be fired by default.

StatusCallback

The StatusCallback attribute allows you to specify a URL for CPaaS to send webhook requests to on each event specified in the StatusCallbackEvent attribute.

StatusCallbackMethod

The StatusCallbackMethod attribute allows you to specify which HTTP method CPaaS should use when requesting the URL in the StatusCallback attribute. The default is POST.

Status Callback HTTP Parameters

The CPaaS parameters passed to your application in its asynchronous request to the StatusCallback URL include all parameters passed in a synchronous request to retrieve RCML when CPaaS receives a call to one of your numbers. The full list of parameters can be found in the RCML Voice Request documentation Request Parameters.

When the call progress events are fired, the Status Callback request also passes these additional parameters:

Parameter Description

Parameter	Description
CallDuration	The duration in seconds of the just-completed call. Only present in the `completed` event.
Timestamp	The timestamp when the event was fired, given as UTC in RFC 2822 format.
CallbackSource	A string that describes the source of the webhook. This is provided to help disambiguate why the webhook was made. On Status Callbacks, this value is always `call-progress-events`.
SequenceNumber	The order in which the events were fired, starting from `0`. Although events are fired in order, they are made as separate HTTP requests and there is no guarantee they will arrive in the same order.

CallDuration

The duration in seconds of the just-completed call. Only present in the completed event.

Timestamp

The timestamp when the event was fired, given as UTC in RFC 2822 format.

CallbackSource

A string that describes the source of the webhook. This is provided to help disambiguate why the webhook was made. On Status Callbacks, this value is always call-progress-events.

SequenceNumber

Making a call to a SIP account

Restcomm will make a call to any SIP account that is reachable. It the example below, the SIP account is listening on port 5060. When you make the call, the SIP phone on which Alice is registered will ring and the hello-play.xml file will be played.

curl -X POST https://mycompany.restcomm.com/restcomm/2012-04-24/Accounts/ACCOUNT_SID/Calls.json  \

Calling a DID number

The above example shows how to make a call to a SIP number. If you want to make a call to a DID one, you must have a registered Restcomm number first. You can register a number by logging into your Restcomm Console and following the steps in the Getting Started Guide.

You can also purchase a number via the IncomingPhoneNumbers API.

Modifying Live Calls

Real time call modification allows you to interrupt an in-progress call and terminate it or have it begin processing RCML from a new URL. This is useful for any application where you want to asynchronously change the behavior of a running call. For example: hold music, call queues, transferring calls, forcing hangup, etc.

Live Call Modification API is supported only for calls created with Dial verb using a RCML application

HTTP POST to a Call

To redirect or terminate a live call, you make an HTTP POST request to an in-progress Call instance resource URI:

/2012-04-24/Accounts/{AccountSid}/Calls/{CallSid}

/2012-04-24/Accounts/{AccountSid}/Calls.json/{CallSid}

The following parameters are available for you to POST request when modifying a phone call:

Request Parameters

Parameter	Description
Url	A valid URL that returns RCML. Restcomm will immediately redirect the call to the new RCML.
Method	The HTTP method Restcomm should use when requesting the above URL. Defaults to POST.
Status	Either canceled or completed. Specifying canceled will attempt to hangup calls that are queued or ringing but not affect calls already in progress. Specifying completed will attempt to hang up a call even if it’s already in progress.
Mute	Either true or flase. Setting value of this parameter to true will mute the call. Setting value of this parameter to false will unmute the call.

Parameter

Description

Url

A valid URL that returns RCML. Restcomm will immediately redirect the call to the new RCML.

The HTTP method Restcomm should use when requesting the above URL. Defaults to POST.

Status

Either canceled or completed. Specifying canceled will attempt to hangup calls that are queued or ringing but not affect calls already in progress. Specifying completed will attempt to hang up a call even if it’s already in progress.

Mute

Either true or flase. Setting value of this parameter to true will mute the call. Setting value of this parameter to false will unmute the call.

Call in-Progress

Note that any call which is currently ringing within a Dial verb is in-progress from the point of view of Restcomm, and thus you must use 'Status=completed' to cancel it.

Optional Parameters

You may POST the following parameters:

Request Parameters

The HTTP method Restcomm should use when requesting the above URL. Defaults to POST.

MoveConnectedCallLeg

If True, Restcomm will move both call legs to the new URL

Description

Prerequisite for the Live Call Modification API is to know the CallSid of the call. The CallSid is generated by Restcomm for every incoming or outgoing call. When we create an outgoing call using the Calls REST API, Restcomm will generate the CallSid and the response will contain the CallSid. For an Incoming call, Restcomm will generate the CallSid, and will include it in the parameters of the GET or POST request to download the RCML from the application server. So the application server, will get the CallSid for this incoming call and can store it for later use.

Steps for an incoming call are the following:

New incoming call to Restcomm
Restcomm generates CallSid and other parameters for this call
Restcomm prepares GET/POST request and attaches the previously prepared parameters
Restcomm sends the GET/POST request to the URL assigned to the DID called
Application server receives the GET/POST request
Application server should store the CallSid along with the rest of the parameters for later use
Application server prepares the response with the appropriate RCML for the given DID and send it back to Restcomm to process it

Given that we have the CallSid available, the next step to modify a live call is to prepare the new POST request to Restcomm with the URL of the new destination application.

Lets assume that initially the Application server prepared an RCML that will connect the incoming call to Bob and that later Bob wants this call to be transferred to Alice. Application Server will have to prepare a new RCML that will dial to Alice, and using the Live Call Modification API, will ask Restcomm to process this new RCML for the incoming call and thus will connect it to Alice.

Here are the steps:

Incoming call - CallSid (1234567890)
Applcation server: - Store CallSid and other parameters - Prepare and send RCML that connects the call to Bob (using Dial verb)
Restcomm process the given RCML and connects incoming call to Bob
Bob wants to transfer the call to Alice and sends the request to Controller (application server)
Application server: - Prepares new RCML with a given URL: http://app.server/CallToAlice that using Dial will dial to Alice - Uses Live Call Modification prepares a new POST request: https://$DOMAIN/restcomm/2012-04-24/Accounts/ACCOUNT_SID/Calls/YOUR_CALL_SID - in the POST requests adds the following parameters: Url=http://app.server/CallToAlice
Restcomm process this Live Call Modification request and redirects the incoming call to the new RCML application (to the new URL)
Eventually the incoming call will be connected to Alice.

Similar, application server can change an incoming call to Bob to a conference call where more participants can be added later. Given that application server already knows the CallSid for the incoming call to Bob

Will prepare a new RCML for the Dial Conference
Will prepare new POST Live Call Modification request for the incoming call to be connected to the new url (that will dial to the conference)
Will then prepare new outgoing call request, using the Calls Rest API that will connect Bob to the conference application URL: - https://$DOMAIN/restcomm/2012-04-24/Accounts/ACCOUNT_SID/Calls` - will pass the following parameters: From=INCOMING_CALL_ID To=client:bob Url=CONFERENCE_APPLICATION_URL
Later application server can create more outgoing call requests, similar to the one above, to invite other clients or sip URLs or PSTN numbers to this conference call

Modifying Live Calls - Example

In order to accomplish this, you need to create a client called alice
Start a SIP phone and register alice
From the terminal run the following curl command
Make sure alice is using the port 5061
The "From=" could be any number of your choice
The Url is the default sample example provided with Restcomm
