Abstract
An apparatus and method are disclosed for processing session initiation protocol (SIP) messages associated with a Voice over IP (VoIP) terminal. An apparatus that incorporates teachings of the present disclosure may include, for example, a network proxy having a controller that manages a communications interface in a communication system. The controller can be programmed to receive from a VoIP terminal a SIP message comprising a request to communicate with a destination point, detect from the SIP message a lack of location information associated with the VoIP terminal, and transmit a location query to one among the VoIP terminal, and a gateway connecting the VoIP terminal to the network proxy. Additional embodiments are disclosed.
