8.4.10.3.6 Step 6: Define IP-to-Tel Routing Rules
The procedure below describes how to configure IP-to-Tel routing rules. These rules route
calls to the previously defined Trunk Groups in ''Step 5: Define Trunk Groups for PSTN
Users'' on page 566.
You need to configure the following rules:
Rule #1: route calls with destination prefix 01 to the E1/T1 trunk/PSTN network (i.e.,
Trunk Group 2)
Rule #2: route all other calls to FXS users (i.e., Trunk Group 1)
To configure IP-to-Tel routing rules:
1. Open the 'Inbound IP Routing Table' page (Configuration tab > VoIP menu > GW
and IP to IP submenu > Routing submenu > IP to Trunk Group Routing).
2. Add a rule for routing calls with destination prefix 01 to the PSTN:
a. In the 'Dest Phone Prefix', enter '01'.
b. In the 'Source Phone Prefix' and Source IP Address' fields, enter an asterisk
symbol (*) to indicate any.
Version 6.2
From the 'Channel Select Mode' drop-down list, select 'By Dest Phone
Number'. This setting sends the call to a specific FXS user according to the
called (destination) number.
From the 'Registration Mode' drop-down list, select 'Per Endpoint'. This
allows the FXS users to register to the device's internal database, using IP
Group 3 (defined in ''Step 3: Define IP Group for PSTN'' on page 562). Since
you disabled 'Classify by Proxy' for this IP Group, FXS users are handled as
though belonging to IP Group 1 and adhere to the same IP-to-IP routing
rules.
From the 'Serving IP Group ID' drop-down list, select '3'.
Click Submit.
In the 'Trunk Group ID' field, enter '2'.
From the 'Channel Select Mode' drop-down list, select 'Cyclic Ascending'.
From the 'Registration Mode' drop-down list, select 'Don't Register'.
From the 'Serving IP Group ID' drop-down list, select '3'.
Click Submit.
