Manipulating Number Prefix

The device supports a notation for adding a prefix where part of the prefix is first extracted
from a user-defined location in the original destination or source number. This notation is
entered in the 'Prefix to Add' field in the Number Manipulation tables (see ''Manipulation'' on
page 145):
x[n,l]y...
where,

x = any number of characters/digits to add at the beginning of the number (i.e. first
digits in the prefix).

[n,l] = defines the location in the original destination or source number where the digits
y are added:
•
n = location (number of digits counted from the left of the number) of a specific
string in the original destination or source number.
•
l = number of digits that this string includes.

y = prefix to add at the specified location.
For example, assume that you want to manipulate an incoming IP call with destination
number +5492028888888 (area code 202 and phone number 8888888) to the number
0202158888888. To perform such a manipulation, the following configuration is required in
the Number Manipulation table:
