JITTERBUFFER()¶
Synopsis¶
Add a Jitterbuffer to the Read side of the channel. This dejitters the audio stream before it reaches the Asterisk core. This is a write only function.
Description¶
Jitterbuffers are constructed in two different ways. The first always take four arguments: max_size, resync_threshold, target_extra, and sync_video. Alternatively, a single argument of 'default' can be provided, which will construct the default jitterbuffer for the given jitterbuffer type.
The arguments are:
max_size: Length in milliseconds of the buffer. Defaults to 200 ms.
resync_threshold: The length in milliseconds over which a timestamp difference will result in resyncing the jitterbuffer. Defaults to 1000ms.
target_extra: This option only affects the adaptive jitterbuffer. It represents the amount time in milliseconds by which the new jitter buffer will pad its size. Defaults to 40ms.
sync_video: This option enables video synchronization with the audio stream. It can be turned on and off. Defaults to off.

exten => 1,1,Set(JITTERBUFFER(fixed)=200,1500)
exten => 1,1,Set(JITTERBUFFER(adaptive)=200,,60)
exten => 1,1,Set(JITTERBUFFER(adaptive)=200,,,yes)
exten => 1,1,Set(JITTERBUFFER(fixed)=default)
exten => 1,n,Set(JITTERBUFFER(disabled)=)
Note
If a channel specifies a jitterbuffer due to channel driver configuration and the JITTERBUFFER function has set a jitterbuffer for that channel, the jitterbuffer set by the JITTERBUFFER function will take priority and the jitterbuffer set by the channel configuration will not be applied.
