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 may store system-wide configuration data and files referenced by the system-wide configuration data. The terminals may further determine whether the system-wide configuration data references a file that is not stored in the terminal, and requesting the file from another terminal of the telephone system in response to determining the terminal does not have a copy of the file.
