Abstract
Systems and methods of setting up a push-to-talk call are provided. When a push-to-talk server receives a request for a push-to-talk call from an originating mobile station, the server sends a push-to-talk call notification to a destination mobile station identified in the request and starts a timer. Upon expiration of the timer the server determines whether the originating mobile station has a traffic channel for the push-to-talk call.
