Abstract
Techniques are provided for assigning extension numbers to Internet Protocol (IP) telephony devices. The techniques include receiving a message from the IP telephony device requesting that an extension be assigned. A port identifier of a port in which the IP telephony device is coupled is determined. Extension numbers are fixed for specific ports. Thus, an extension number for the port identifier of the port is determined. The extension number is then assigned to the IP telephony device. For example, a MAC address for the IP phone is assigned to the extension number.
