4.10 Step 10: Configuring Voice Coders
The device communicates with the Mediation server using either the G.711 A-law or G.711
µ-law (Mu-Law) voice coder. In addition, silence suppression can be enabled per coder,
which is recommended for improving the performance with the Mediation server. The
procedure below shows how you can change the default coder.
To configure the voice coder and silence suppression:
1. Open the Coders page (Configuration tab > VoIP menu > Coders And Profiles >
Coders).
Figure 4-23: Coders Table Page
2. From the 'Coder Name' drop-down list, select the required coder.
3. From the 'Silence Suppression' drop-down list, select Enable.
4. Click Submit.
Note: The Coder Table above represents Coder Group ID 0. To apply this Coder
Group to an SBC entity, you need to assign it in the corresponding IP Profile
(see Section 4.5 on page 28).
