Virtual Facilities
Accessing a Virtual Facility
Dial access is provided by dialing the VF code (#190-#199, including the “#”), followed by
the destination telephone number.
● Example:
— The user dials the following VF code and associated destination telephone
number.
#192 12125551643.
— The stored VFN associated with VF code #192 is defined as
2222 ✶ 333 ✶ 444.
— The first four digits (2222) represent the FAC for a tie trunk group to a remote
PBX.
— The ✶ represents a 1.5 second pause.
— The next three digits (333) represent the security code required by the remote
PBX, indicating that you have permission to access their facilities.
— The ✶ represents a 1.5 second pause, as the remote PBX checks the validity
of your security code.
— The final three digits (444) represent the FAC required by the remote PBX to
access their Band 5 WATS trunks.
— Since “#5” was not embedded within this VFN, the destination telephone
number (12125551643) will be transmitted after the WATS access code.
VF codes may be included in numbers stored in REP DIAL buttons, System Speed Dialing
codes, and Personal Speed Dialing codes if the VF code is used at the beginning of these
numbers. VF codes may not be assigned to FACILITY buttons and may not be embedded in
other virtual facility numbers.
VFs may be used in ARS routing patterns just as if they were physical facilities.
Considerations
VFs enhance the Automatic Route Selection feature by increasing the number of facility types
available for use in routing patterns.
Using ARS ensures that the least-cost facility is used to
complete each call. User intervention is minimized and associated user dialing errors are
essentially eliminated.
In addition, in those systems where users are permitted dial access to VFs, user dialing of
long digit strings is minimized, as are the associated dialing errors.
