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.
