    Telephony.dial()

    Non-standard
    This feature is not on a current W3C standards track, but it is supported on the Firefox OS platform. Although implementations may change in the future and it is not supported widely across browsers, it is suitable for use in code dedicated to Firefox OS apps.

    This API is available on Firefox OS for internal applications only.

    The dial() method of the Telephony interface dials a phone number and returns a new TelephonyCall object representing the new call.

    Syntax

    The new syntax is promise-based, and resolves with the TelephonyCall object for the new call:

    myTelephony.dial(number or MMICode,serviceId).then(function(myTelephonyCall) {
      // do something with the new call
    });
    

    The original syntax (Firefox 1.3 and below) was just a regular non-promise method.

    var myTelephonyCall = myTelephony.dial(number or MMICode,serviceId);
    

    Parameters

    number
    A string indicating the phone number to dial.
    MMI code
    A string indicating the MMI code to dial (e.g. *123#).
    serviceId Optional
    The id of the mobile service you want to use to make the call. If not specified, the default value for the device is used.

    Returns

    A promise that resolves with a TelephonyCall object.

    Examples

    // Telephony object
    var tel = navigator.mozTelephony;
    
    // Place a call
    tel.dial("123456789").then(function(call) {
      call.id;
    });
