8.4.10.5.2 Step 2: Define Allowed Coders
The procedure below describes how to configure an Allowed Coders Group for ITSP. This
ensures that the device uses only the coder G.729 on its outbound leg to the ITSP. This
Allowed Coder Group is later assigned to the IP Profile of the ITSP (in ''Step 2: Define an
IP Profile'' on page 569).
¾ To configure an Allowed Coder Group:
1. Open the 'Allowed Coders Group' page (Configuration tab > VoIP menu > SBC
submenu > Allowed Coders Group).
2. From the 'Allowed Coders Group ID' drop-down list, select '1'.
3. From the 'Coder Name' drop-down list, select 'G.729'.

8.4.10.5.3 Step 3: Define IP Profiles

These IP Profiles need to be assigned the following:
IP Profile for LAN users must be assigned Coder Group #1 (i.e., G.711)
IP Profile for ITSP must be assigned Coder Group #2 and Allowed Coder Group #1
These IP Profiles are later assigned to the IP Groups for LAN users and ITSP (in ''Step 4:
