Asterisk developer's documentation

Music on Hold Configuration


; Music on Hold -- Sample Configuration
;cachertclasses=yes ; use 1 instance of moh class for all users who are using it,
                    ; decrease consumable cpu cycles and memory
                    ; disabled by default

; valid mode options:
; files		-- read files from a directory in any Asterisk supported 
;		   media format
; quietmp3 	-- default 
; mp3 		-- loud
; mp3nb		-- unbuffered
; quietmp3nb	-- quiet unbuffered
; custom	-- run a custom application (See examples below)

; =========
; File-based (native) music on hold
; =========
; This plays files directly from the specified directory, no external
; processes are required. Files are played in normal sorting order
; (same as a sorted directory listing), and no volume or other
; sound adjustments are available. If the file is available in
; the same format as the channel's codec, then it will be played
; without transcoding (same as Playback would do in the dialplan).
; Files can be present in as many formats as you wish, and the
; 'best' format will be chosen at playback time.
; The path specified can be either an absolute path (starts with '/'),
; or a relative path; relative paths are interpreted as being relative
; to the 'astdatalibdir' in asterisk.conf, which defaults to
; /var/lib/asterisk.
; If you are not using "autoload" in modules.conf, then you
; must ensure that the format modules for any formats you wish
; to use are loaded _before_ res_musiconhold. If you do not do
; this, res_musiconhold will skip the files it is not able to
; understand when it loads.

;digit=#        ; If this option is set for a class, then when callers are
;               ; listening to music on hold, they can press this digit, and
;               ; they will switch to listening to this music class.
;sort=random    ; Sort the files in random order

;sort=alpha     ; Sort the files in alphabetical order.  If this option is
;               ; not specified, the sort order is undefined.

; =========
; Other (non-native) playback methods
; =========

; Note that with mode=custom, a directory is not required, such as when reading
; from a stream.
;application=/usr/bin/mpg123 -q -r 8000 -f 8192 -b 2048 --mono -s

;application=/usr/bin/streamplayer 888

; mpg123 on Solaris does not always exit properly; madplay may be a better
; choice
;application=/site/sw/bin/madplay -Q -o raw:- --mono -R 8000 -a -12
