Asterisk. Конфигурационный файл mgcp.conf.

Описываются опции, касающиеся протокола MGCP.
Протокол контроля медиа-шлюзов MGCP (Media Gateway Control Protocol) имеет лишь примитивную поддержку в Asterisk. Поэтому использовать MCGP-каналы в Asterisk при производственной эксплуатации рекомендуется только в режиме тестирования.

;---------------------- DIGIT TIMEOUTS ----------------------------
firstdigittimeout = 30000 ; default 16000 = 16s
gendigittimeout = 10000 ; default 8000 = 8s
matchdigittimeout = 5000 ; defaults 3000 = 3s

;------------------------------ JITTER BUFFER CONFIGURATION --------------------------
; jbenable = yes ; Enables the use of a jitterbuffer on the receiving side of a
; MGCP 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 MGCP channel can accept jitter,
; thus an enabled jitterbuffer on the receive MGCP side will only
; be used if the sending side can create jitter and jbforce is
; also set to yes.

; jbforce = no ; Forces the use of a jitterbuffer on the receive side of a MGCP
; 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 MGCP
; 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".
