70 CHAPTER 2: DIAL PLAN
V82 (Digits column) The letter V (required, and must be a capital letter)
indicates that this is a VPIM connection, and the
82 indicates that the user must dial 82 to access
the VPIM connection and then dial the extension
the user wants to reach.
You can select any number of digits for a site
code. The selected number must not conflict with
other dial plan entries. This example assumes that
82 is not used in any other way in the dial plan.
Long digit sequences can annoy telephone users
and create the opportunity for dialing errors.
Min (5) Max (5) Indicates that the total digit sequence dialed by
the user is 5 digits. The first two digits are the site
code (82 in this example) and the remaining 3
digits are the destination extension.
Class (WAN) Indicates that this call is classified as WAN. All
VPIM calls have this classification.
Priority (0) This field is unused by the dial plan; the default
value is zero (0).
Route (532) In this example, the VPIM connection to the other
NBX system uses route 532. The route number
must be unique in the dial plan and in the range of
1–32768.
DestinationRoute Create 532 Atlanta VPIM Connection
This command creates route number 532 and
gives it the name Atlanta VPIM Connection.
DestinationRouteEntry Create 532 1 *0003
This command (mandatory for all VPIM routes)
assigns route 532 to the extension list *0003.
DestinationRouteOperation Create 532 1 1 stripLead 3
For DestinationRoute 532, entry 1, this command
creates operation 1, which removes the first three
digits, including the letter V, from the digit string,
leaving only the extension that the user dialed.
DestinationRouteOperation Create 532 1 2 prepend 10*234*101*222*
For DestinationRoute 532, entry 1, this command
creates operation 2, which places the string
10*234*101*222* in front of the extension. This
string represents the IP address of the target NBX
system. You must use the star character (*) to
separate the fields within the IP address and to
separate the IP address from the extension field.
