Abstract: Methods and apparatus to implement voice over Internet protocol (VoIP) phones are disclosed. A disclosed example method includes detecting removal of a first user-replaceable network interface from a first port of a phone, the first network interface to communicate with a gateway using a first VOIP; detecting insertion of a second user-replaceable network interface into the first port of the phone, the second network interface to communicate with the gateway using a second VOIP, the second VOIP being different from the first VOIP; receiving a driver for the second network interface via a second port defined in the housing of the phone, the driver to enable the second network interface to communicate with the gateway using the second VOIP, the driver being received after a boot procedure to initialize the phone; and initializing the second network interface based on the driver.

Abstract: Methods and apparatus to implement voice over Internet protocol (VoIP) phones are disclosed. A disclosed example VoIP phone comprises a phone housing, a voice over Internet protocol (VoIP) processor located in the phone housing, and a bay defined in the phone housing and dimensioned to receive a user-replaceable network interface.

Abstract: A feature server provides an abbreviated dialing feature via an internet protocol based network to facilitate abbreviated dialing between a first phone system that serves a first location and a second phone system that serves a second location. A routing table at the first phone system stores a number range of a voice over internet protocol customer local area network located at a third location. The routing table includes instructions to route abbreviated-dialed calls to a first integrated access device. The feature server receives a query from the second phone system when an abbreviated-dialed call originating from the second phone system is not recognized by the second phone system. The abbreviated-dialed call is communicated to the internet protocol based network by a second integrated access device.

Abstract: An abbreviated dialing feature over a Voice over Internet Protocol (VoIP) platform facilitates abbreviated dialing between a first phone system that serves a first customer location and a second phone system that serves a second customer location. The first and second phone systems may comprise two Centrex groups, two PBXs or a Centrex group and a PBX.

Abstract: A method of facilitating calls includes receiving a message at a mediation server from a first device associated with a first packet-based network, the message relating to a second device associated with a second packet-based network. The method also includes identifying first connection information relating to the first device, where the first connection information includes a set of call receipt rules that relates to a format of packet-based data that is acceptable to the first device. The method also includes sending, in response to the message, second connection information related to the second device from the mediation server to the first device.

Abstract: A system and method for facilitating packetized calls between managed networks are disclosed. In one embodiment of a system incorporating teachings of the present disclosure, a mediation server may be associated with and maintain an information store holding a first collection of connection information for a first plurality of devices associated with a first managed internet protocol network and a second collection of connection information for a second plurality of devices associated with a second managed internet protocol network. The devices may be capable of receiving voice over internet protocol calls and the connection information for a given device may include a unique address and a call receipt rule. In operation, the mediation server may receive a query seeking appropriate connection information for a called device associated with the first managed internet protocol network.

Abstract: A Voice over Internet Protocol (VoIP) feature server provides a remote worker feature over a VoIP platform of an IP network. The remote worker feature facilitates an individual, who is assigned a telephone number at his/her home PBX, to receive telephone service from a remote PBX using the same telephone number.
