asterisk 1.4.42 Функция Record() вырезает паузы и тишину

Запись активируется в cron-e строкой с сылкой на скрипт:

15 16 * * 1,2,3,4,5 <--->root<--->/usr/local/bin/rec.sh [внутренний номер 120] [кол-во минут]

rec.sh файл содержит:

#!/bin/bash # This script executed by CRON in $1 $2 # Parameters are PHONE NUMBER you have to record voice message from and DURATION in minutes CALLFILE=echo ${RANDOM}${RANDOM}.${1} FILENAME=date +%F-%H%M-test` FILEPATH="/var/test" FILEFORMAT="wav"

 # Call file creation and moving to execute 
 echo "Channel: SIP/kamailio-in/$1" > /tmp/${CALLFILE} 
 echo "Application: Record" >> /tmp/${CALLFILE} 
 echo "Data: $FILENAME.$FILEFORMAT|0|$((${2}*60))|noanswer" >> /tmp/${CALLFILE} 


 mv /tmp/${CALLFILE} /var/spool/asterisk/outgoing 
 sleep $((${2}*60+10)) 
 mv /var/lib/asterisk/sounds/${FILENAME}.${FILEFORMAT} ${FILEPATH} 

 # Parameters -V QUALITY (0..9 less is the better) 
 lame -S -V 9 --scale 15 ${FILEPATH}/${FILENAME}.${FILEFORMAT} ${FILEPATH}/${FILENAME}.mp3 

 # This part will remove files older than 60 days from asterisk:/var/MW 
 find ${FILEPATH}/* -mtime +60 -delete 

 exit 0`

В $FILEPATH - пишется формат .wav и .mp3 с вырезкой всех пауз и тишины. Это делает неприятным восприятие записи. В чем проблема?
