Receiving a TMO Group Call

Unless it is engaged in a call, your MTP850 Ex/MTP810 Ex will receive the Group Call. To answer the call, press and hold PTT.

Your MTP850 Ex/MTP810 Ex shows the group name and the caller’s private number or alias if previously stored in your contact list.

Receiving a TMO Broadcast Call

The Broadcast Call (also called Site Wide Call) is a high-priority Group Call from the console operator (or dispatcher) to all users. The MTP850 Ex/MTP810 Exs are configured to monitor a Broadcast Call, but users cannot talk back.

The Broadcast Call pre-empts an on-going Group Call that has the same (or lower) call priority.
