TelephonyCallGroup.hangUp()

The hangUp() method of the TelephonyCallGroup interface hangs up the entire conference call, i.e. every TelephonyCall object within it.

Syntax

myTelephonyCallGroup.hangUp().then(function() { ... });

Parameters

None.

Returns

A promise that resolves with void.

Examples

// Create your Telephony object
var tel = navigator.mozTelephony;

// Make two calls; assume they are both answered
var call1, call2;
tel.dial(number1).then(call => call1 = call);
tel.dial(number2).then(call => call2 = call);

// Add both calls to the conference call
// Two entries will appear in conference.calls (call1, call2)
// but nothing in tel.calls
var conference = tel.conferenceGroup;
conference.add(call1, call2);

conference.hangUp().then(function() {
  // run some code after the conference has
  // finished hanging up
});

// You could just run conference.hangUp()
// if no further action is required
