MMICall

The MMICall interface of the Web Telephony API represents an MMI call, allowing us to receive the result of the call.

An MMICall is when you call a special number that contains MMI (Man-Machine Interface) codes (such as * or #.) Such a call can be initiated to perform specific functions on a phone (such as forwarding all calls to a specified number, checking phone credit balance, or displaying the phone's IMEI (Internatiol Mobile Equipment Identifier.)) You can find more details at What’s the difference between USSD, MMI and SS codes?

Properties

MMICall.result Read only

Returns a promise that resolves to an MozMMIResult object containing information associated with the success status of the MMI call.

Examples

// Telephony object
var tel = navigator.mozTelephony;

// Place a call
tel.dial("<code>*123#</code>").then(function(call) {
  call.result.then(function(MMIResult) {
    // do something with MMI result
  });
});
