Configuring NSF Codes
This appendix explains how to configure MeetingPlace with the correct NSF codes when necessary.
Configuring NSF codes on the MeetingPlace server may be necessary when making outdials directly to
the PSTN (without an intervening PBX) on trunks using the ISDN protocol.

Note
For the most part, NSF codes are used only in Canada and the United States.
Note
To determine if this system requires NSF code configuration, ask the telephone service provider if the
system uses NSF codes. This should have been determined prior to installation and recorded in
worksheet F-1 in the MeetingPlace Audio Server 5.2 Installation Planning Guide.

MeetingPlace needs to be configured with the proper NSF code information to operate with the PSTN.
Failure to set up the NSF codes properly (or not configure them at all) has two main effects:

•
Failed outdials — Outdials directly to the PSTN are rejected. However, outdials via an intervening
PBX probably still work.

•
Higher phone service costs — Outdials might work directly to the PSTN but a carrier’s standard or
premium rates may be applied, rather than discounted rates. As part of provisioning a service, a
carrier will require that customers use specific NSF code information. This information must be sent
out on every call to get a specific discounted service rate for the call.

Understanding NSF codes
The ISDN protocol allows telephone service providers to add to the ISDN protocol with their own
custom protocol extensions. These extensions allow carriers to provide various localized services that
are not defined in the general ISDN specifications. These extensions are contained in the Network
Specific Facility (NSF) Information Element (IE). They are generally called “NSF” codes for short. The
NSF code is also called the Binary Facility Coding Value (BFCV).
