A system and method for providing advanced voice services in a wireless communications network. The system also interfaces to an Internet Protocol (IP) network to perform the advanced voice services for mobile units in the IP network and includes a protection mechanism against Voice-over-IP (VoiP) Denial-of-Service (DoS) attacks utilizing Advanced Group Services (AGS).

VoIP denial-of-service protection mechanisms from attack

A Push-to-Talk-over Cellular (PoC) implementation for use in a wireless communications network, wherein one or more servers interface to the wireless communications network to perform the PoC call sessions. Both the servers and the mobile units that use the PoC call sessions communicate with each other using SIP/IP (Session Initiation Protocol/Internet Protocol) control messages within the wireless communications network, and one or more of the servers switches RTP/IP (Realtime Transport Protocol/Internet Protocol), RTCP/IP (Realtime Transport Control Protocol/Internet Protocol), or MBCP/IP (Media Burst Control Protocol/Internet Protocol) voice packets for the PoC call sessions between the mobile units across the wireless communications network.
