When configuring the adaptive jitterbuffer, the target_extra value not only could not be set from the configuration, but was not even being set to its proper default. This value is required in order for the adaptive jitterbuffer to work correctly. To resolve this a config option has been added to expose this value to the conf files, and a default value is provided when no config specific value is present. git-svn-id: https://origsvn.digium.com/svn/asterisk/trunk@249893 65c4cc65-6c06-0410-ace0-fbb531ad65f3

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
|
|
; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of an
|
|
; OSS channel. Defaults to "no". An enabled jitterbuffer will
|
|
; be used only if the sending side can create and the receiving
|
|
; side can not accept jitter. The OSS channel can't accept jitter,
|
|
; thus an enabled jitterbuffer on the receive OSS side will always
|
|
; be used if the sending side can create jitter.
|
|
|
|
; jbmaxsize = 200 ; Max length of the jitterbuffer in milliseconds.
|
|
|
|
; jbresyncthreshold = 1000 ; Jump in the frame timestamps over which the jitterbuffer is
|
|
; resynchronized. Useful to improve the quality of the voice, with
|
|
; big jumps in/broken timestamps, usually sent from exotic devices
|
|
; and programs. Defaults to 1000.
|
|
|
|
; jbimpl = fixed ; Jitterbuffer implementation, used on the receiving side of an OSS
|
|
; channel. Two implementations are currently available - "fixed"
|
|
; (with size always equals to jbmax-size) and "adaptive" (with
|
|
; variable size, actually the new jb of IAX2). Defaults to fixed.
|
|
|
|
; jbtargetextra = 40 ; This option only affects the jb when 'jbimpl = adaptive' is set.
|
|
; The option represents the number of milliseconds by which the new
|
|
; jitter buffer will pad its size. the default is 40, so without
|
|
; modification, the new jitter buffer will set its size to the jitter
|
|
; value plus 40 milliseconds. increasing this value may help if your
|
|
; network normally has low jitter, but occasionally has spikes.
|
|
|
|
; jblog = no ; Enables jitterbuffer frame logging. Defaults to "no".
