Abstract
A system for providing Quality of Service (QoS) for voice over internet protocol (VoIP) provides a remote station with the address of an SIP proxy server. The initiates a VoIP service flow by sending an Invite to the proxy server via a base station. If the service flow is authorized, the remote station transmits a request to the base station to establish a service flow having a selected QoS. The proxy server also provides a dynamic address for a voice gateway. Once the service flow is established, the remote station transmits RTP packets to the designated voice gateway using the service flow having the designated QoS level.
