Figure III-4-13 Codecs
If you want to use codec G729, we recommend buying a license key and input it here.

dropped due interference from other lower priority traffic. When the network capacity is
insufficient, QoS could provide priority to users by setting the value.
Figure III-4-14 Qos
Note: It’s recommended that you configure the QoS in your router or switch instead of
NeoGate side.
5) Response Code
You can change the response code on NeoGate TA to the one you want before sending it
