1. A system comprising:
- an enterprise network comprising an enterprise network infrastructure coupled to a wide area network, a plurality of enterprise telephony resources, and a call control system capable of supporting telephony services for the enterprise telephony resources;
a computing device comprising a wireless interface supporting wireless local area network communication protocols and a network interface operable to couple to the wide area network and to establish a communication session with the enterprise network across the wide area network, the computing device further comprising a controller operable to scan for telephony handsets using the wireless interface, to establish a wireless link with a detected telephony handset, and to relay packets between the telephony handset and the enterprise network using the communication session; and
a telephony handset comprising a wireless interface supporting one or more wireless communication protocols and operable to establish a wireless link with the computing device, the handset further comprising a controller operable to register with the call control system in the enterprise network and to manage packet-based telephony services supported by the call control system.

Abstract
A system includes an enterprise network having a call control system that manages telephony services for wireless handsets. At a remote site, a computing device establishes a secure, wireline communication session with the enterprise network. The computing device also establishes wireless, packet-based links with one or more handsets. The device acts as a relay to enable the handsets to receive telephony services managed by the enterprise network even though outside of the service area of the enterprise network.
