19.3.2.6 Step 6: Define IP-to-Tel Routing Rules

The procedure below describes how to configure IP-to-Tel routing rules. In the example,
you need to configure the a rule that routes IP calls with destination prefix 9 to the E1/T1
trunk/PSTN network (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. In the 'Dest Phone Prefix', enter "9".
3. In the 'Source Phone Prefix' and 'Source IP Address' fields, enter the asterisk symbol
"*" to indicate any.
4. In the 'Trunk Group ID' field, enter "1".
5. Click Submit.

19.3.3 SBC Vocoder Transcoding

This section describes how to configure an SBC coder transcoding scenario. This example
is not based on the previous examples and only describes the configuration of the coder
transcoding feature itself. It assumes that the other elements such as SRD's and IP Groups
have been configured according to your network environment. This example implements
the Allowed Coder Groups feature, which allows you to block the use of coders that are not
defined in the Allowed Coders Group list.
This example assumes the following:

Device deployed at an enterprise, interfacing between enterprise's Network-1 IP-PBX
and enterprise's Network-2 IP-PBX

Network-1 IP-PBX uses G.711 coder

Network-2 IP-PBX uses only G.729 coder
