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