Configuration
Fig. 18 Codeсs options
Enter a number of frames per packet in the neighboring edit box FPP with due regard to the
endpoint capability and buffer size. Information about codec frame sizes is given in the table
below.
Table 2 Frame sizes by codecs
Codec Frame size
G.729 10 ms
G.729A 10 ms
G.723 30 ms
G.711-aLaw 1 ms
G.711-uLaw 1 ms
GSM 06.01 20 ms
Therefore, if an endpoint can accept no more than, say, 60ms worth of audio per packet, for
G.711 you can enter the value 60; for G.723 it will be 2 (60/30 = 2); for G.729 it would be 6
(60/10 = 6).
Note: Please, remember that for G.711 codecs it makes sense to enter “frames per packet”
values in multiples of ten only.
You can increase/decrease codec precedence in the table by clicking up- and down-arrow
buttons.
Click to move the codec record up one line and increase the codec precedence.
Click to move the codec record down one line thus decreasing the codec precedence.
