In a simplex call, the radio limits the time you can continuously talk in a group call without interruption,
according to a provisioned value. You are warned shortly before the talk time expires.

Call Restoration in Private Call

If the radio roams while you are the transmitting party in a private call, the announced cell reselection is
employed (if possible). Call restoration procedures are performed in the new cell.
If you are not the transmitting party, the radio employs an unannounced cell reselection, followed by
the call restoration procedures.
