function addVoIPPushTokenUpdatedListener(listener): EventSubscription;

Defined in: Calls.ts:926

Subscribes to VoIP token updated events.

Fired when the VoIP push token is received or updated after calling registerVoIPPush. Also fired if the token is invalidated (with token being undefined).

Parameters

Parameter	Type	Description
listener	(event) => void	Callback invoked when the VoIP token updates.

Returns

EventSubscription

A subscription that can be removed by calling .remove().

Example

const subscription = addVoIPPushTokenUpdatedListener((event) => {
  if (event.token) {
    console.log('New VoIP token:', event.token);
    sendTokenToBackend(event.token);
  } else {
    console.log('VoIP token invalidated');
  }
});

See

• useVoIPPushToken — React hook that uses this internally; prefer it in components.
• registerVoIPPush — must be called once before any token updates fire.
