1. A telephony handset comprising:
- a speaker;
a microphone;
a wireless interface supporting 802.11 wireless communication protocols, the wireless interface operable to establish a wireless link with a computing device that is coupled to a communication network, the computing device having a communication session established across the communication network with a remote enterprise network; and
a controller operable register with a call control system in the remote enterprise network and to manage packet-based telephony services supported by the call control system, the controller further operable, during calls, to packetize voice information received using the microphone, to transmit formed packets to the enterprise network, to receive audio packets from the enterprise network, and to generate audio based on data in the received audio packets using the speaker.

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.
