Auto start freeswitch in cent OS

In CategoryLinux, Voice Over IP

After compiling and  installing freeswitch on centOS from freeswitch source files , we can just copy  /usr/src/freeswitch/build/freeswitch.init.redhat   file to /etc/init.d directory and   correct the freeswitch path entries  to make it start at boot time .

copy the file to init.d directory and  add permissions

#cp /usr/src/freeswitch/build/freeswitch.init.redhat /etc/init.d/freeswitch

#chmod 755 /etc/init.d/freeswitch

edit the file  and correct the freeswitch path entries . On my  freeswicth  test server the entries are like below




save the file  and  add it to auto start services list


chkconfig –level 345 freeswitch on


now chkconfig –list freeswitch should show something like below

<25>:chkconfig –list freeswitch
freeswitch 0:off 1:off 2:off 3:on 4:on 5:on 6:off


If we restart the system it should start free-switch automatically .

netstat -ptuln  command output will show if  free-switch is listening to the ports






A2billing and Astersik

In CategoryVoice Over IP

Finallly I got the Asterisk+freeswitch  in a single system up and running  with fusion pbx as front end for freeswitch  and A2billing for Astersik .

You may wonder why we needed this complicated  single box all-in one setup . I wanted to use this setup for our office internal PBX   as well as integrating DID number purchase panel and for international calls.



I have got few issues while configuring  this system .

Issue 1 :


After installing freepbx and asterisk on teh same system i wanted to change free switch sip port from 5060 to any other port  as asterisk is already using the port 5060 .

So i edited the file vars.xml

# vi /usr/local/freeswitch/conf/vars.xml



Just after installing a2billing , i renamed the default web directory  /var/www/html/a2billing  to something else  and  it caused the extensions/pins i created not registering and I could not reload asterisk from a2billing interface .

I realized that this is  because of missing short link for /var/lib/asterisk/agi-bin/lib -> /var/www/html/renamed/common/lib

# cd /var/lib/asterisk/agi-bin

#ln -s /var/www/html/a2billing/common/lib  lib


 Issue 3:

I wanted a2billing take care of asterisk configuration files and not to restart asterisk manually when there is a change ,

for this i turn of  “Asterisk real time” in system settings –>global list —>global




Every-time I place a outbound call , a2billing plays the audio saying ” enter the number you wish to dial and press the pound key”. I dont want this but  place the calls directly .

under systemsettings–>Global list –> Agi-conf1  , I changed below values to ‘NO’


say_timetocall =no


Issue 5:

By enabling debug level =4  in agi-conf , I understood why my outbound calls are not connecting .

by disabling caller id authentication in agi-conf,  i made it work finally .

cid_enable = NO

below is the log from a2billing log files

Uninstalling freepbx and asterisk manually

In CategoryVoice Over IP


First stop asterisk . If you are running freepbx enter the command “amportal stop”


killall -9 safe_asterisk

killall -9 asterisk
then unload zaptel drivers

lsmod | grep zaptel

if this returns blank , skip this step if it retruns something like below then remove the drivers with modprobe command

zaptel 214820 2 wcfxo,wctdm
crc_ccitt 2113 1 zaptel
we can remove zaptel modules in reverse order
modprobe -r wcfxo
modprobe -r wctdm
repeat this for all other zaptel submodules

modprobe -r zaptel
Now confirm that all zaptel drivers have been removed ,if you enter “lsmod | grep zaptel” it will return nothing.

Now remove asterisk directories
rm -rf /etc/asterisk
rm -f /etc/zaptel.conf
rm -rf /var/log/asterisk
rm -rf /var/lib/asterisk
rm -rf /var/spool/asterisk
rm -rf /usr/lib/asterisk

Uninstalling  freepbx  is as simple as just removing the freepbx web directories and drop the database
rm -rf /var/www/html/panel
rm -rf /var/www/html/admin


Changing default passwords of elastix

In CategoryVoice Over IP

Elastix , which is a free forked version of asterisk pbx product comes with integrated ready to use add-ons like a2billing  ( billing module for voip/telephony ) , vtigercrm  etc.,


After installing we must change default passwords for elastix admin , a2billing and vitigercrm admin .

This can be done easily while installation time ( with new versions ) , or after logging into the panel with default passwords( older versions).


But  there was serious security bug ( i think it is patched now ) with elastix , where somebody can hack  the elastix box with the default password of built in user ‘asteriskuser’  and  able to make calls.


Here are the steps i followed to change astersikuser password


Step1 :

changing  password in database

-ssh to elastixbox with root privileges

-connect to sql  console  by typing  # mysql -u root -p

-now enter the mysql root password ( you can find this in /etc/elastix.conf  and you can even change it by typing #mysqladmin -u root -p’oldpassword‘ password ‘newpassword‘)


mysql> show databases;
| Database           |
| information_schema |
| asterisk           |
| asteriskcdrdb      |
| meetme             |
| mya2billing        |
| mysql              |
| roundcubedb        |
| test               |
| vtigercrm510       |
9 rows in set (0.00 sec)

mysql> use mysql;
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed

mysql> set password for ‘asteriskuser’@’localhost’ = PASSWORD(‘newpassword‘);


change asteriskuser password in /etc/amportal.conf

now run command  # /usr/src/AMP/ to apply the changes


type #grep -r “asteriskuser” /etc/asterisk/*   to find files with asteriskuser entries and change the password to newpassword


[root@vm2 ]# grep -r “asteriskuser” /etc/asterisk/*
/etc/asterisk/cdr_mysql.conf:user = asteriskuser
/etc/asterisk/res_mysql.conf:dbuser = asteriskuser




*replace newpassword with your own password
