Codec Profiles <audioProfile/>

The following profile attributes can be adjusted for each of the five supported codecs. In the table, x=G711Mu, G711A, G722, G7221, G7221C, and G729AB, Lin16, Siren14, and Siren22.

voice.audioProfile.x.payloadSize

10, 20, 30, ...80

Preferred Tx payload size in milliseconds to be

 

 

provided in SDP offers and used in the

 

 

absence of ptime negotiations. This is also the

 

 

range of supported Rx payload sizes.

 

 

The payload size for G7221, G7221C, Siren14,

 

 

and Siren22 are further subdivided.

 

 

 

voice.audioProfile.x.jitterBufferMin

20, 40, 50, 60,

The smallest jitter buffer depth (in milliseconds)

 

... (multiple of

that must be achieved before play out begins

 

10)

for the first time. Once this depth has been

 

 

achieved initially, the depth may fall below this

 

 

point and play out will still continue. This

 

 

parameter should be set to the smallest

 

 

possible value which is at least two packet

 

 

payloads, and larger than the expected short

 

 

term average jitter. The IP4000 values are the

 

 

same as the IP30x values.

 

 

 

voice.audioProfile.x.jitterBufferShrink

10, 20, 30, ...

The absolute minimum duration time (in

 

(multiple of 10)

milliseconds) of RTP packet Rx with no packet

 

 

loss between jitter buffer size shrinks. Use

 

 

smaller values (1000 ms) to minimize the delay

 

 

on known good networks. Use larger values to

 

 

minimize packet loss on networks with large

 

 

jitter (3000 ms).

 

 

 

voice.audioProfile.x.jitterBufferMax

>

The largest jitter buffer depth to be supported

 

jitterBufferMin,

(in milliseconds). Jitter above this size will

 

multiple of 10,

always cause lost packets. This parameter

 

<=300 for IP

should be set to the smallest possible value

 

320, 330, 430,

that will support the expected network jitter.

 

501,550, 600,

 

 

601, and 650

 

 

<= 200 for IP

 

 

301
