Abstract

A system, apparatus, and method for introducing services into a Push to Talk (PTT) environment. Requests for services are generated and transmitted via requesting PTT clients. The request is received at a PTT server, which forwards the request to a PTT application server recognized by the PTT server as another PTT client. The requested service is performed at the PTT application server, and a result is generated in response. The result is transmitted from the PTT application server to the requesting PTT client by way of the PTT server.
