G.729 Codec
The G.729 Codec page allows you to register and manage your G.729 codec license keys. The G.729 Codec is
an industry standard algorithm that compresses and decompresses a digital audio stream. Applied to Voice
over IP (VoIP) calls, G.729 compresses the audio data to use significantly less network bandwidth than a
standard or uncompressed VoIP call. This compression allows for more calls to be carried without increasing
network capacity and allows voice to travel on limited-bandwidth connections that would otherwise not
support VoIP.
Click Register a G729 License key on this Appliance to cause the CSG to download the End User License
Agreement (EULA). Read the EULA carefully. If you agree to its terms, click I agree to the above License.
Complete the G.729 Codec License Information form in full. The G.729 License Key field should begin with
“G729-”. Then click Register. Your registration information will be securely sent to AMX’s registration
server.
The registration process may take a few minutes to complete. A message box will appear to let you know once
the firmware has finished updating. You must reboot your CSG for these changes to take effect. Click Options
on the left menu, select the Reboot tab, and then click Reboot Now to reboot your appliance. Rebooting your
CSG will terminate any active calls.
If the registration process fails, please confirm that you have entered the G.729 license key correctly, and that
a firewall is not blocking the CSG from communicating with AMX’s registration server on TCP port 443.
If you do not currently own a G.729 codec license, click Buy new G729 Codec Licenses to be directed to a
page where you can purchase G.729 codec licenses.
The CSG can support a maximum of 8 simultaneous calls being transcoded with
G.729. Calls using G.729 which are not being transcoded (pass-thru) do not count
towards that total.
