;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
;jbenable = yes                 ; Enables the use of a jitterbuffer on the receiving side of a
                                ; Dongle 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 Dongle channel can't accept jitter,
                                ; thus an enabled jitterbuffer on the receive Dongle side will always
                                ; be used if the sending side can create jitter.

;jbforce = no                   ; Forces the use of a jitterbuffer on the receive side of a Dongle
                                ; channel. Defaults to "no".

;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 a Dongle
                                ; channel. Two implementations are currently available - "fixed"
                                ; (with size always equals to jbmaxsize) 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".
