In the Destination Phone Prefix box, enter a prefix for this IP Routing Table entry.
The prefix can be 1 to 40 digits long. Any telephone number routed to the VoIP Gateway that
starts with these digits is sent to the IP Telephony gateway that has the IP Address entered in
the box to the right of this field.
6 In the IP Address box, enter the IP address of the IP Telephony gateway to which calls that
match this entry are sent.
The IP Telephony gateway to which the calls are sent must be compatible with the VoIP
Gateway. Examples of compatible IP telephony gateways are: another VoIP Gateway,
Business Communications Manager and Meridian 1 IPT.
7 Repeat steps 4 and 6, for each IP Routing Table entry.

Note: When entering a number, you can create an entry that represents multiple
numbers using the following notation:
• [n-m] represents a range of numbers
• [n,m] represents multiple numbers
• x represents any single digit
• * represents any digit or multiple digits
• # represents the end of a number
• For example:
[5551200-5551300] represents all of the numbers from 5551200 to 5551300
[2221,2231,2241] represents the numbers 2221, 2231 and 2241
54324* represents any number that starts with 54324
54324xx represents a 7 digit number that starts with 54324
123[100-200]* represents numbers that starts with 123100 to numbers that start
with 123200.
When the dialed number matches the number you enter here, the rules in this number
manipulation table entry are applied.
The VoIP Gateway matches the rules starting at the top of the table. For this reason,
enter more specific rules above more generic rules. For example, if you enter 551* in
entry 1 and 55* in entry 2, the VoIP Gateway applies rule 1 to numbers that starts with
551 and applies rule 2 to numbers that start with 550, 552, 553, 554, 555, 556, 557,
558 and 559. However if you enter 55* in entry 1 and 551* in entry 2, the VoIP
Gateway applies rule 1 to all numbers that start with 55 including numbers that start
with 551.
Note: You can have maximum of 50 entries in the IP Routing Table.
