摘要:
A method of routing a telephone call includes receiving an indication, at a handset device 112, to initiate a telephone call. It is then determined, preferably by the handset device 112, 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 134. On the other hand, if the telephone call is an emergency services telephone call, it is routed to a local gateway 116 without first accessing the proxy server 134.

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.
摘要:
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.
