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.
