[general]

interval=15 ; Number of seconds between trying to connect to devices

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

; dongle required settings[dongle0]audio=/dev/ttyUSB1 ; tty port for audio connection;

; or you can omit both audio and data parameters and use imei=123456789012345 and/or imsi=612849384756451; imei and imsi must contain exactly 15 digits !

; imei/imsi discovery is available on Linux only

; if you set audio and data parameter together with imei and/or imsi, audio and data is used.; you can use both imei and imsi together. In this case exact match by imei and imsi is required.
