Installing VoipMonitor on Trixbox and Elastix

Using Internet SIP trunking services with a VOIP phone system is incredibly cost effective. The only problem is the unreliability of the Internet. We’ve been expreimenting with several tools for monitoring phone call quality but VoipMonitor has been the most useful. Some of the most useful features are:

  • Creates packet capture of each phone call. This is really useful because you get more┬ámanageable┬ácapture files, not one monster files containing all calls.
  • It logs all calls to a MySQL database and calculates several important metrics like MOS. If you need an example of a bad quality call to send to your provider you can just sort the call table by MOS. Anything under 4.0 probably has some jitter or lag in the audio.
Here are the steps to install VoipMonitor (these are just slightly modified from
Install all dependencies through yum.
yum install subversion libmysql++-dev libvorbis-devel mysql-devel libpcap-devel php5-mysql php5-gd
Install libpcap. You need a version > 1.0 so the version in the yum repo is not current enough.
tar xzf libpcap-1.1.1.tar.gz
cd libpcap*
make install
Install the mysql client that VoipMonitor uses to connect to MySQL
tar xzf mysql++-3.0.9.tar.gz
cd mysql++-3.0.9
make install
cp /usr/local/lib/ /usr/lib/
Install VoipMonitor
tar zxf voipmonitor-2.0.tar.gz
cd ../voipmonitor-2.0
make install
cp /usr/local/lib/libpcap.* /usr/lib
Next you need to create the MySQL database. Here we use the mysql command line client. You can also use phpMyAdmin or Webmin if you have access to it.
We always specify a MySQL root user password during the installation of Trixbox and Elastix so we just log in as the root user. Use mysql -u root and then you will be prompted for a password.
     mysql> create database voipmonitor;
     mysql> exit
Create the database tables.
cat cdrtable.sql | mysql voipmonitor

Start up VoipMonitor. The u and p switches are for the MySQL username and password. Call VoipMonitor with no arguments to see a list of possible command line switches.

voipmonitor -i eth0 -SRG -h localhost -b voipmonitor -u root -p passw0rd

Error occurring

checking whether -lnsl is needed… no
checking for MySQL library directory… configure: error: Didn’t find mysqlclient library in ‘/usr/lib64 /usr/lib /usr/lib64/mysql /usr/lib/mysql /usr/local/lib64 /usr/local/lib /usr/local/lib/mysql /usr/local/mysql/lib /usr/local/mysql/lib/mysql /usr/mysql/lib/mysql /opt/mysql/lib /opt/mysql/lib/mysql /sw/lib /sw/lib/mysql’

any solution for that

thanks in advance


Make sure you run the first command to install all the requirements:

yum install subversion libmysql++-dev libvorbis-devel mysql-devel libpcap-devel php5-mysql php5-gd
