    ; volume levels, mutes, etc.

    ; ----------------------------- 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".

; These entries can also be contained in the comment field of the image,
; which is a lot more convenient to manage.
; E.g. for jpeg you can write them with wrjpgcom (part of libjpeg).
; The format to define keys is
;	region = <event> <shape> x0 y0 x1 y1 h
; where <event> is the event to be generated (a digit, pickup, hangup,...)
; <shape> is the shape of the region (currently 'rect' and 'circle' are
; supported, the latter is really an ellipse),  x0 y0 x1 y1 are the
; coordinates of the base of the rectangle or main diameter of the ellipse,
; (they can be rotated) while h is the height of the rectangle or the other
; diameter of the ellipse.
