A system and method for setting up a call between an originator and a destination are disclosed. A request for an interconnect call is sent to a push-to-talk (PTT) location register. The PTT location register determines whether the destination is currently available. If it is determined that the destination is not currently available, a call failure message to sent to the originator. If it is determined that the destination is available, then a PTT call is setup between the originator and destination. An interconnect call is then setup between the source and destination and the PTT call is torn down.
