Codec
The codec used for each call will be negotiated with the peer party before each session, and therefore many
codecs will not be included in your default configuration. The default codec is G.729A, it occupies little
bandwidth while maintaining good voice quality.
If your upstream speed is only 64Kbps, using G.711_A codec is not recommended. It is better to have at least
256Kbps upstream if you would like to use G.711_A.
Priority
There are five priorities for you to configure the codec priority in the order you
preferred. Priority 1 means the first priority and priority 5 means the last.
Codec
Select the codec type from the drop-down list.
Packetization Time
Select the length of the digital voice segment that each packet holds. The default is 20
millisecond packets. Selecting 10 millisecond packets enhances the voice quality, as
less information is lost due to packet loss, but doubles the load on the network traffic.
DTMF
Select the method of DTMF tone generation from the drop-down list.
