asterisk users - Jun 2009 - gap between Playback and Queue

Hi,

I have a 2/3 second gap between the end of a welcome message played with
Playback and the start of the Queue music. Here is the dialplan:

	exten => ${EXTEN},1,NoOp($EXTEN)
	exten => ${EXTEN},n,SIPAddHeader(Alert-Info: Ring_CCC)
	exten => ${EXTEN},n,Set(CALLERID(name)=${MYCID})
	exten => ${EXTEN},n,Answer()
	exten => ${EXTEN},n,Wait,1
	exten => ${EXTEN},n,Playback(/usr/local/share/asterisk/sounds/welcome)
	;; ---- slight gap (silence) here -----
	exten => ${EXTEN},n,Queue(ccc|t|||${QUEUEWAITTIME})

The welcome sound does end correctly after the last word.

Any idea?

Thanks,

If this is a recorded sound, you might want to truncate it with lame or
audacity.  It is quite common in my shop as we record using the phones.

Thanks for this suggestion.

The problem was indeed a silence at the beginning of my musiconhold
tracks. Audacity did a fine job and fixed my problem.

Well, at least this did not add to the wait time of your callers :)
It should be possible to do silence detection/removal automagically using
sox as well - see e.g.
