20.2.10 Step 10: Configure Destination Phone Number Manipulation

This step defines how to manipulate the destination phone number. The IP-PBX users in
our example scenario use a 4-digit extension number. The incoming calls from the ITSP's
have different prefixes and different lengths. This manipulation leaves only the four digits of
the user's destination number coming from the ITSP's.

To configure destination phone number manipulation rules:
1. Open the Destination Phone Number Manipulation Table for IP -> Tel calls page
(Configuration tab > VoIP menu > GW and IP to IP > Manipulations > Dest
Number Tel->IP).
2. Configure Index #1 to manipulate destination number of IP calls received from ITSP-A.
The phone number of calls received with prefix +1919 (i.e., from ITSP-A) are removed
except for the last four digits:
•
'Destination Prefix': enter the prefix "+1919".
•
'Source Prefix': enter the asterisk (*) symbol to indicate all sources.
•
'Number of Digits to Leave': enter "4" to leave only the last four digits.
3. Configure Index #2 to manipulate destination number of IP calls received from ITSP-B.
The phone number of calls received with prefix 0200 (i.e., from ITSP-B) are removed
except for the last four digits:
•
'Destination Prefix': enter the prefix "0200".
•
'Source Prefix': enter the asterisk (*) symbol to indicate all sources.
•
'Number of Digits to Leave': enter "4" to leave only the last four digits.
