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.
