Hacks and Patches

Converting audio files for use in Asterisk

Resample a stereo wav into a mono 8000Hz 16 bit wav:
sox infile.wav -c mono -r 8000 -b 16 outfile.wav

Convert a properly formatted wav (8000Hz, 16bit mono) file to gsm:
sox infile.wav outfile.gsm

Converting mp3 to slin

mpg123 -w file.wav file.mp3
sox file.wav -t raw -r 8000 -s -2 -c 1 file.sln

Converting wav to slin

sox file.wav -t raw -r 8000 -s -2 -c 1 file.sln

Upgrading asterisk 1.4 to 1.6

NoOp updates

/NoOp

:%s/\(NoOp,\)\(.*\)$/NoOp(\2)/
sed -e 's/\(NoOp,\)\(.*\)$/NoOp(\2)/'

pipe character to comma

:%s/|/,/g

ExecIf updates

/ExecIf

:%s/\(ExecIf(\)\(\$\[.*\]\),\(.*\),\(.*\)$/\1\2?\3(\4)/
sed -e 's/\(ExecIf(\)\(\$\[.*\]\),\(.*\),\(.*\)$/\1\2?\3(\4)/'

Deprecated stuff - dialplan

Using AWK to find individual calls

The below scripting will find all calls to the extension 11175 and print all the details for each call.

grep Dial /var/log/asterisk/full | grep macro-stdexten-v3 | grep "11175," | awk -F\[ '{print $3}' | awk -F\] '{print $1}' | while read x; do echo ""; echo ""; echo ""; echo "identifier: $x"; echo ""; echo ""; echo ""; grep "\[$x\]" /var/log/asterisk/full; done



grep "Called .*11175" /var/log/asterisk/full | awk -F\[ '{print $3}' | awk -F\] '{print $1}' | while read x; do echo ""; echo ""; echo ""; echo "identifier: $x"; echo ""; echo ""; echo ""; grep "\[$x\]" /var/log/asterisk/full; done



grep "Called .*11175" /var/log/asterisk/full | awk -F\[ '{print $3}' | awk -F\] '{print $1}' | while read x; do echo ""; echo ""; echo ""; echo "identifier: $x"; echo ""; echo ""; echo ""; grep "\[$x\]" /var/log/asterisk/full; done | grep -A 5 -e "Called .*11175"

Finding hung channels

Asterisk 1.4,1.6
asterisk -rx "core show channels concise" | awk -F ! '{print $1,$11}'

asterisk -rx "core show channels concise" | awk -F ! '{print $1,$11}' | while read x y; do if [ $y -gt 60 ] || [ $y -lt 0 ]; then echo "$x - `expr $y / 60` minutes `expr $y % 60` seconds"; fi ; done

Asterisk 1.2
asterisk -rx "show channels concise" | awk -F : '{print $1,$11}'
