Telephony.dialEmergency()

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

The dialEmergency() method of the Telephony interface dials an emergency 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.dialEmergency(number,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.dialEmergency(number,serviceId);

Parameters

number
A string indicating the emergency number to dial.
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.dialEmergency("911").then(function(call) {
  call.id;
});
