[asterisk-users] Script to softly restart Asterisk each midnight to clean locked channels

[Mindaugas Kezys]

As Asterisk has inner problems and channels very often locks we have such
script to restart Asterisk each midnight.

 

We (our clients) mostly use v1.4.18.1. We can't upgrade to newer versions
because there are too much changes which would brake our system
(realtime/sip/iax2/cdr/etc/etc).

 

Script soft hangups all alive channels in dirty way then kills Asterisk and
starts it up. 

 

Hope it will be useful to somebody.

 

Corrections/comments welcome.

# tell Asterisk do not accept new calls

asterisk -rx 'stop gracefully' >/dev/null

 

# read all channels

asterisk -rx 'core show channels verbose' | sed '1d' > /tmp/f1

cat /tmp/f1 | awk '{split ($0,a," "); print a[11]}' > /tmp/f2 

 

 

# hangup all alive channels

for i in `cat /tmp/f2`; do 

    asterisk -rx "soft hangup $i " > /dev/null 

done 

 

# let asterisk to stop by itself

sleep 5

 

# kill remainings

killall -9 safe_asterisk

killall -9 asterisk

 

# start fresh and ready to work!

/etc/init.d/asterisk start

 

 

# clean

rm -rf /tmp/f1 

rm -rf /tmp/f2
