<jb_max perm="PERMISSIONFLAGS">VALIDVALUE</jb_max>

Description

This is the enhanced jitter buffer maximum value in milliseconds.
That means the jitter buffer will not go above this value. Be careful in selecting this value, as very high values will introduce too much latency, although that could improve the jitter and waiting longer for out of sequence packets.
With V8.9.3 this setting is also used on snom720 and snom760.

Valid Values

A reasonable number for maximum jitter buffer size in milliseconds preferably in multiples of 20 like 120,140,160,...,200 and so on. It should be kept at the ideal value of 240. Values that are too high could introduce too much latency although that may be required in networks with a huge jitter and a lot of late out of sequence packets.

Default Value

• snom3x0: 240
• snom720/snom760: 300
