Abstract
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.
Claims13
A telephone system, comprising:
- a first telephone terminal that is a voicemail enabled Internet Protocol (IP) telephone, the first telephone terminal conducts a telephone call over an IP network, and broadcasts on the IP network a beacon signal having a first configuration identifier for system-wide configuration data stored by the first telephone terminal;
- and
- a second telephone terminal that is a voicemail enabled IP telephone, the second telephone terminal conducts a telephone call over the IP network with the first telephone terminal, and receives the beacon signal via the IP network, the second telephone terminal transmits to the first telephone terminal a master handoff request having a second configuration identifier for a system-wide configuration data stored by the second telephone terminal, and the second telephone terminal assumes a master coordinator role in response to receiving an acknowledgement from the first telephone terminal.
A telephone system including a plurality of telephone terminals, the system comprising:
- a first telephone terminal including a base unit, that base unit sends and receives voice signals over an Internet Protocol (IP) network of the telephone system, transmits and receives beacon signals via the IP network, and determines whether system-wide configuration data for the telephone system stored by the first telephone terminal is up-to-date based upon a first configuration identifier of the beacon signals, and the first telephone terminal is a public switched telephone network (PSTN) enabled telephone terminal;
- and
- a second telephone terminal that transmits to the first telephone terminal a master handoff request having a second configuration identifier for a system-wide configuration stored by the second telephone terminal, and assumes a master coordinator role in response to receiving an acknowledgement from the first telephone terminal, and the second telephone terminal is a PSTN enabled telephone terminal.
