Abstract
A system and method for emulating phone extensions in a packet telephony distribution system include using a gateway and an adapter. Signaling protocols between the gateway and the adapter provide procedures to enable typical analog phone system characteristics such as a dial tone and a line-in-use indicator. During an incoming or outgoing call, users of multiple phones on the packet telephony distribution system can make and receive calls or join a call in progress using methodologies commonly used for typical analog phone systems.
