Dial Plan

The dial plan consists of a series of dialling rules, or strings, that determine whether what
the user has dialled is valid and when the VSP726A should dial the number.
There are three different types of dial plans available: general, Call Restriction, and
Emergency.
In the case of overlapping dial plan definitions between Emergency, Call Restriction, and
the general dial plan, the following priority (high to low) applies:
1. Emergency
2. Call Restriction
3. General
For example, in order to restrict a regular user to dial extensions in the 9xx range while
having 911 as the emergency number, use the following dial plans:
 Emergency dial plan = 911
 Call Restriction dial plan = 9xx
 General dial plan = xxx
A user who dials 920 will be unable to complete the call, and the message 920 is a
restricted number will appear on the phone screen. A user who dials 911 will complete
an emergency dial.
Numbers that are dialled when forwarding a call—when the user manually fowards
a call, or a pre-configured number is dialled for Call Forward All, Call Forward–No
Answer, or Call Forward Busy—always bypass the dial plan.
Dialling rules must consist of the elements defined in the table below.
Element Description
x Any dial pad key from 0 to 9, including # and *.
[0-9] Any two numbers separated by a hyphen, where the second number is
greater than the first. All numbers within the range or valid, excluding # and *.
x+ An unlimited series of digits.
, This represents the playing of a secondary dial tone after the user enters the
digit(s) specified or dials an external call prefix before the comma. For
instance, "9,xxxxxxx" means the secondary dial tone is played after the user
dials 9 until any new digit is entered. "9,3xxxxxx" means only when the digit
3 is hit would the secondary dial tone stop playing.
PX This represents a pause of a defined time; X is the pause duration in
seconds. For instance, "P3" would represent pause duration of 3 seconds.
When "P" only is used, the pause time is the same as the Inter Digit Timeout
(see "SIP Account Management" on page
