• 'Source Phone Prefix': enter the asterisk (*) symbol to indicate all sources.
• 'Dest IP Group ID': select 1 to indicate the destination IP Group to where the calls
must be sent, i.e., to ITSP-A.
• 'IP Profile ID': enter "1" to indicate the IP Profile configured for G.711.
6. Configure Index #5 to route IP calls received from the IP-PBX to ITSP-B:
• 'Source IP Group ID': select 3 to indicate received (inbound) calls identified as
belonging to the IP Group configured for the IP-PBX.
• 'Dest Phone Prefix' and 'Source Phone Prefix': enter the asterisk (*) symbol to
indicate all destinations (besides Japan) and all sources respectively.
• 'Dest IP Group ID': select 2 to indicate the destination IP Group to where the calls
must be sent, i.e., to ITSP-A.
• 'IP Profile ID': enter "1" to indicate the IP Profile configured for G.711.
7. Configure Index #6 to route dialed calls (four digits starting with digit 4) from IP-PBX
to remote IP-PBX users. The device searches its database for the remote users
registered number, and then sends an INVITE to the remote user's IP address (listed
in the database):
• 'Source IP Group ID': select 3 to indicate received (inbound) calls identified as
belonging to the IP Group configured for the IP-PBX.
• 'Dest Phone Prefix': enter the "4xxx#" to indicate all calls dialed from IP-PBX that
include four digits and start with the digit 4.
• 'Dest IP Group ID': select 4 to indicate the destination IP Group to where the calls
must be sent, i.e., to remote IP-PBX users.
• 'IP Profile ID': enter "1" to indicate the IP Profile configured for G.711.
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.
