AT&T R1V2 manual Virtual Facilities

Virtual Facilities

A Virtual Facility (VF) is a call-routing facility which is not defined by the physical facility (trunk) over which calls are routed. Instead, the facility is defined by a combination of access codes, authorization codes, and coded characters that allow special handling of the destination telephone number. VFs can be used to automatically route calls via other carrier networks, private networks, or tie trunks.

Virtual Facilities can also be used in ARS patterns to ensure that users who place these types of calls use the route (the virtual facility) the system administrator has defined. For more information, see the System 25 Reference Manual.
