ABSTRACT:
A method and system for routing a push-to-talk (PTT) call in a communications network is disclosed. A PTT call request is received at a regional call processor of the communications network, where the PTT call request includes an address for a called party with a first user part and a second domain part. The regional call processor consults a table to determine whether the second domain part is associated with the communications network. The regional call processor routes the PTT call request to a central call processor of the communications network if the second domain part is associated with the communications network and routes the PTT call request to a gateway if the second domain part is not associated with the communications network.
