Abstract
In a push-to-talk communication system, a domain name server transfers a registration server role, call server role, and media server role. A first server receives the registration server role and responsively registers push-to-talk users and maintains a first time of day. A second server receives the call server role and responsively establishes push-to-talk calls and maintains a second time of day. A third server receives the media server role and responsively transfers push-to-talk media and maintains a third time of day. A management system receives and processes data from the servers to verify that their time of day is synchronized and to verify that the servers are performing their assigned push-to-talk roles.
