Abstract
A user self-expandable extension network system and its dialing and answering processes are applied to an extension network which consists of a plurality of extensions. An extension will send a detecting signal to locate the host phone and regard the host phone as a session initiation protocol (SIP) proxy server after receiving the reporting signal of the host phone. Therefore, the extension can be dialed or receive a phone call without being set up by the assistance of a professional technician.
