Abstract
The present invention provides a system and method of modifying policy settings in an electronic device. An embodiment includes a plurality of access stations, each capable of wirelessly transmitting across a geographic region. A mobile electronic device, capable of roaming between regions is operable to establish a wireless link with the access stations. The device is owned by an office which sets communication policies determining through which access stations mobile device can place voice calls. This policy is stored on an office server as a database and periodically transmitted to the device as the device makes contact with the office server over the internet. Hence, the device maintains a copy of this policy database. When placing a voice call, the device first determines which access station is serving the region it is located in and then determines whether it is allowed to place a call through that access station using its policy database.
