ABSTRACT:
Controlling access to a facility includes sending a program and profile for facility services to a user's portable device. The services have telephones connected via a local area network (“LAN”), so a call originating on the LAN to such a telephone may be completed on the LAN without accessing a wide area telephone network (“WAN”). The program is executed on the user's portable device so that the device operates in a facility mode. In this mode, the device displays services from the profile, so that the user can select a service and easily place telephone calls to it solely over the LAN. Responsive to the user's service selection, in a normal operating sub-mode the user's portable device places a call via the WAN using a longer telephone number and in a local operating sub-mode the user's portable device places the call via the LAN using a shortcut number.
