Abstract: Methods and media are provided for offering telecommunications features to wireless devices through the use of a wireless exchange unit. The wireless exchange unit serves as an access point onto a larger wireless telecommunications network through use of a high-speed internet connection. The wireless exchange unit includes an access point base transceiver station (BTS) and an integrated application server. The integrated application server includes a session proxy, a home application server, and a voice application server. The wireless devices can access features such as, among other things, reduced-digit dialing, call rollover, and alternate message notification. For connections between devices local to the wireless exchange unit, the larger telecommunications network resources need not be utilized, therefore reducing congestion and improving performance.
