A method of routing a telephone call includes receiving an indication, at a handset device, to initiate a telephone call. It is then determined, preferably by the handset device, whether the telephone call is an emergency services telephone call. If the telephone call is not an emergency services telephone call, it is routed to a proxy server. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gatewaywithout first accessing the proxy server

Telephone system and method for reliable emergency services calling

A Session Initiation Protocol (SIP) device includes one or more voice ports configured to provide voice services; one or more data ports configured to provide data services; firewall logic configured to filter incoming traffic; and quality of service (QoS) logic configured to provide QoS services for traffic transmitted from the SIP device.

Integrated customer premises equipment device

An approach is provided for supporting integrated voice and data services over a common Session Initiation Protocol (SIP)-based Customer Premise Equipment (CPE) device. The device includes a network interface that receives a call from a calling party device to a called party device. Also, the device has signaling conversion logic configured to convert between Session Initiation Protocol (SIP) signaling and circuit-switched telephony signaling to support the call, wherein addressing information of the calling party device is preserved in the conversion. The called party device includes one of a telephone station and a SIP client. The device further includes a voice port coupled to the signaling conversion logic and configured to communicate selectively with the telephone station; and a data port configured to communicate selectively with the SIP client.

An IP telephony client initiates and manages multimedia sessions. The client includes a user interface, an application interface, and a protocol stack. The application interface provides an interface between the protocol stack and the user interface and helper applications. The protocol stack packages messages received from the application interface and parses messages received from other parties or prospective parties. The application interface converts incoming messages to appropriate application programming interfaces (APIs) and sends incoming payloads to the appropriate helper application.
