Abstract
When a user of a subscriber unit (SU) originates a dispatch, or Push-to-Talk (PTT), non-local call with a target SU, a communication system serving the originating SU notifies the originating SU that the call is a non-local call before establishing the call. By notifying the originating SU as to whether the call is a non-local call, a user of the originating SU may make an informed decision as to whether to incur costs associated with a non-local dispatch or PTT call before completing the call.
