Parameter Description
Any SIP incoming call whose destination number matches the prefix defined in the ‘Destination Phone
Prefix’ field
and its source number matches the prefix defined in the adjacent ‘Source Phone Prefix‘ field and
its source IP address matches the address defined in the ‘Source IP Address’ field, is assigned to the trunk
group entered in the field to the right of these fields.
IP to trunk group routing can be performed according to any combination of source /
destination phone prefixes and source IP address, or using each independently.
For available notations that represent multiple numbers (used in the prefix columns), see
Dialing Plan Notation .
Trunk Group ID In each of the Trunk Group ID fields, enter the trunk group ID to
which calls that match these prefixes are assigned.
Profile ID Enter the number of the IP profile that is assigned to the routing
rule.
Internal DNS Table
The internal DNS table, similar to a DNS resolution, translates hostnames into IP addresses.
This table is used when hostname translation is required (e.g., ‘Tel to IP Routing’ table). Two
different IP addresses can be assigned to the same hostname. If the hostname isn’t found in
this table, the gateway communicates with an external DNS server.
Assigning two IP addresses to hostname can be used for alternative routing (using the ‘Tel to
IP Routing’ table).
To configure the internal DNS table:
1
Open the ‘Internal DNS Table’ screen ( Protocol Management menu > Routing Tables
submenu > Internal DNS Table option); the ‘Internal DNS Table’ screen is displayed.
Figure 39 Internal DNS Table Screen
2 In the ‘DNS Name’ field, enter the hostname to be translated. You can enter a string up
to 31 characters long.
3
In the ‘First IP Address’ field, enter the first IP address that the hostname is translated to.
4
In the ‘Second IP Address’ field, enter the second IP address that the hostname is
translated to.
5 Repeat Steps 2 to 4, for each Internal DNS Table entry.
