An approach is described for providing shared trunking between a telephony gateway and an end office switch. The telephony gateway processes a packetized voice call, and interfaces a shared trunk to an end office switch (e.g., Class 5 switch) configured to switch calls over a circuit-switched telephone network. The trunk utilizes out-of-band signaling (e.g., Primary Rate Interface (PRI) signaling) in support of call establishment or teardown of the packetized voice call.

Method and system for supporting shared local trunking

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.

Method and apparatus for providing integrated voice and data services over a common interface 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 Initation 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.
