Parameter
Description
G.711 / G.722 / G.723 /
G.729 Jitter Buffer Range
(ms)
Indicates the delay, in milliseconds, used to buffer G.711, G.722,
G.723, and G.729 voice packets received from the IP network. Voice
packets sent over the IP network may incur different delays due to
network load or congestion. The jitter buffer helps to smooth out the
delay variation in the arriving voice packets and maintain voice quality
at the receiving end.
The default values for G.711 are 10 min. to 100 max milliseconds.
The default values for G.722 are 10 min. to 100 max milliseconds.
The default values for G.723 are 30 min. to 480 max milliseconds.
The default values for G.729 are 10 min. to 480 max milliseconds.
G.711 / G.722 / G.729
RTP Packet Length (ms)
Lets you configure the length of the RTP packets for G.711, G.722,
and G.729 in milliseconds. The RTP packet length can be set to 10,
20 or 30 milliseconds.
The smaller the packet length, the larger the bandwidth required.
Setting Codec Priority
In MaxCS 7.5, you can set codec priorities for each Codec Profile.
During codec negotiation, the highest-priority codec that the receiving end supports will be used. Therefore,
you should sort the Selected Codec list by priority, from top to bottom. Use the Up and Down buttons to do this.
Prioritize this profile’s
codecs by arranging codecs
top (highest priority) to
bottom (lowest priority)
