In this example, the first rule adds 972 prefix to all numbers starting with 03. The second rule
first deletes four digits from all numbers starting with 1001 and then the digit 5 is added as
prefix. The third rule deletes all digits except for the last four, from all numbers starting with
123451001 and adds the digit 8 as a prefix.

5876, and number 1234510012001 is changed to 82001.
Tel to IP Routing Table
Using the Tel to IP Routing table is mandatory if the Gateway operates without a proxy
server. It contains up to 50 rows. Each row associates a called phone number prefix with a
destination IP address. The routing table can also be used for fallback routing if
communication with the proxy server is lost. The IP addresses listed in the table can also be
used for security. If security feature is enabled (SecureCallFromIP = 1) the Gateway will
accept calls coming only from these addresses.
To set the Tel to IP Routing table, follow these steps:
1
On the sub-menu bar on the top, click Tel to IP Routing . The Tel to IP Routing screen
opens.
2
Define the appropriate routing rules (see the following figure).
