Register Device Push Token

Registers an Android device push token for incoming call push delivery. Successful registration returns a deviceId that should be stored for device-level push token lifecycle management.

Signature

// Callback version
fun registerDevicePushToken(
  pushToken: String,
  callback: (Exception?, String?) -> Unit
)

// Suspend version
suspend fun registerDevicePushToken(
  pushToken: String
): String

Parameters

Parameter	Type	Required	Description
pushToken	string	Yes	FCM push token for the current device/app install

Return Type

Returns deviceId in callback/coroutine completion on success.

Usage Example

 // Callback
 client.registerDevicePushToken("PushToken") { err, deviceId ->
     when {
         err != null -> {  } // handle error
         else -> println(deviceId)
     }
 }

 // Coroutine
 try {
     val deviceId = client.registerDevicePushToken("PushToken")
     println(deviceId)
 }
 catch (e:Error) {
     // Handle Error in registering push token
 }

Errors

Notes

• This action is Android-only and should be called after session creation
• Persist returned deviceId so you can unregister token mappings when needed
• For inbound call pushes, pair registration with VoiceClient.getPushNotificationType(...) and processPushCallInvite
• iOS uses registerVoipToken; Web does not expose push token registration in Voice API
