Get RTPEngine source from GitHub repository:

cd /usr/src

git clone https://github.com/sipwise/rtpengine.git rtpengine

cd rtpengine

Compile and install the daemon

cd /usr/src/rtpengine/daemon/

make

cp -fr rtpengine /usr/sbin/rtpengine

cp -fr rtpengine /usr/local/bin/rtpengine

Compile and install iptables extension

cd /usr/src/rtpengine/iptables-extension

make all

cp -fr libxt_RTPENGINE.so /usr/lib64/xtables/.

Compile and install the kernel module xt_RTPENGINE

cd /usr/src/rtpengine/kernel-module
make

cp -fr xt_RTPENGINE.ko /lib/modules/`uname -r`/extra/xt_RTPENGINE.ko

depmod -a
modprobe -v xt_RTPENGINE

Check if the kernel module loaded properly:

lsmod | grep xt_RTPENGINE

Make to load the module at the boot time:

echo "# load xt_RTPENGINE module"  >> /etc/modules-load.d/rtpengine.conf

echo "xt_RTPENGINE" >> /etc/modules-load.d/rtpengine.conf

Check if RTPEngine is accessible:

ls -l /proc/rtpengine/control | grep root

Should see:

–w–w—-. 1 root root 0 Oct 16 10:32 /proc/rtpengine/control

ls -l /proc/rtpengine/list

-r–r–r–. 1 root root 0 Oct 16 10:32 /proc/rtpengine/list

Install configuration file

Get your external IP (with ‘ip addr’ for example)

In the following command change 111.111.111.111 to your external IP

echo "OPTIONS=\"-i 111.111.111.111 -n 127.0.0.1:2223 -m 10000 -M 60000 -L 4 --log-facility=local1 --table=8 --delete-delay=0 --timeout=60 --silent-timeout=600 --final-timeout=7200 –offer-timeout=60 --num-threads=12 --tos=184 –no-fallback\"" > /etc/sysconfig/rtpengine

Configure RTPEngine log

echo "local1.*  -/var/log/rtpengine/rtpengine.log;clean_template" >> /etc/rsyslog.conf

mkdir -p /var/log/rtpengine

touch /var/log/rtpengine/rtpengine.log

Configure logrotate

echo "/var/log/rtpengine/rtpengine.log {

daily

rotate 4

missingok

dateext

copytruncate

}" > /etc/logrotate.d/rtpengine

Disable logging to /var/log/messages

perl -pi.bak -e 's#(\s+)\/var\/log\/messages#;local1.none$1/var/log/messages#' /etc/rsyslog.conf

systemctl restart rsyslog
