Jitter Buffer
At this page to set the basic operating parameters used by the PBX core to use the voice jitter
buffer during SIP channel calls as below
：
Enables Jitterbuffer
Enabled using the jitter buffer feature. The PBX
program will use the jitter buffer on the SIP receiver
only when the jitter buffer function is enabled and
forced.
No Not enabled (system default).
Yes Enabled.
Forces Jitterbuffer
Force the SIP channel to use the voice jitter swapping
area function.
No Not enabled (system default).
Yes Enabled.
Enables Jitterbuffer Frame Logging
No Not enabled (system default).
Yes Enabled.
Jitterbuffer Implementation
Fixed
The size is always equal to the Max Length
of the Jitterbuffer setting (system default).
Adaptive Variable size.
Max Length of the Jitterbuffer
The maximum length of the jitter buffer in
milliseconds.
Jump in the Frame Timestamps
The frame timestamp of the jump resynchronization
jitter buffer. Helps improve voice quality and typically
sends a large number of jump/interrupt timestamps
from different devices and programs. The default
value is 1000.
Represents time by the new Jitterbuffer The time (in milliseconds) that the new jitter buffer
represents. This parameter affects the Jitterbuffer
only when it is set to adaptive. The default value of
this option is 40. If it is not modified, it means that
the size of the new jitter buffer is set to Max Length
of the Jitterbuffer setting plus 40 milliseconds. If your
network typically has low jitter, but occasionally
peaks, increasing this value may help.

Codec
At this page to set the PBX core to preset the voice codec parameters that the other party will
use when receiving a call request.
Codecs Preset allowed voice codec.
