Peer-to-peer internet protocol telephone system with system-wide configuration data

摘要

Various embodiments of the invention provide a Peer-to-Peer (P2P, Internet Protocol (IP) telephone system. The telephone system includes a plurality of terminals coupled together via an IP network. The terminals cooperate with one another to provide telephony features without a dedicated central controller such as a PBX and/or a KSU controller. The terminals further cooperate with one another to maintain system-wide configuration data for the telephone system.

主权项

1. A telephone system, comprising a plurality of telephone terminals, wherein:
a first telephone terminal of the plurality of telephone terminals is configured to conduct a telephone call over an Internet Protocol (IP) network, and to broadcast on the IP network a beacon signal comprising a first configuration identifier for system-wide configuration data stored by the first telephone terminal; a second telephone terminal of the plurality of telephone terminals is configured to conduct a telephone call over the IP network with the first telephone terminal, and to receive the beacon signal via the IP network, wherein the first telephone terminal is further configured to store a revision history of configuration identifiers, to determine whether a second configuration identifier provided by a verification request from the second telephone terminal matches a configuration identifier of the revision history, and to remove the second telephone terminal from the telephone system if a match of the second configuration identifier is not found in the revision history, wherein the first telephone terminal is further configured to transmit to the second telephone terminal an update notification in response to the verification request if the second configuration identifier provided by the verification request matches a configuration identifier of the revision history of configuration identifiers, wherein the revision history of configuration identifiers are transferable from the first telephone terminal to the second telephone terminal at a master handoff request by the second telephone terminal to the first telephone terminal, and wherein the system-wide configuration data comprises data used to configure the plurality of telephone terminals for one or more telephony features of the telephone system.
