Installing RTPEngine on Ubuntu 14.04:

First of all Clone the RTPengine project from GitHub. To clone the RTPengine use below command.

apt-get install git
git clone https://github.com/sipwise/rtpengine.git rtpengine

git clone https://github.com/sipwise/rtpengine.git rtpengine
Cloning into ‘rtpengine’…

Resolving deltas: 100% (4798/4798), done.
Checking connectivity… done.

Then enter into rtpengine directory and run ./debian/flavors/no_ngcp in order to remove any NGCP dependencies.

cd rtpengine
./debian/flavors/no_ngcp

Then we need to run the dpkg-buildpackage command. But I got lot of dependencies.. here is the list.

dpkg-buildpackage

dpkg-buildpackage
………
Unmet build dependencies: debhelper (>= 5) iptables-dev (>= 1.4) libcurl4-openssl-dev | libcurl4-gnutls-dev | libcurl3-openssl-dev | libcurl3-gnutls-dev libglib2.0-dev (>= 2.30) libpcre3-dev libxmlrpc-c3-dev (>= 1.16.07) | libxmlrpc-core-c3-dev (>= 1.16.07) markdown
dpkg-buildpackage: warning: build dependencies/conflicts unsatisfied; aborting
dpkg-buildpackage: warning: (Use -d flag to override.)

Let’s Install dependencies one by one.

apt-get install debhelper
apt-get install iptables-dev
apt-get install libcurl4-openssl-dev
apt-get install libpcre3-dev libxmlrpc-core-c3-dev
apt-get install markdown

Then try to build RTPengine once again.
dpkg-buildpackage

Now I got one more dependency libglib2.0-dev. so let’s install this one also
apt-get install libglib2.0-dev

Now once again try to build RTP Engine.
dpkg-buildpackage

Success! Build Completed, Few .deb files are created in the parent directory(use cd .. ).
Let’s Install those deb files..

cd ..
dpkg -i ngcp-rtpengine-daemon_4.1.0.0+0~mr4.1.0.0_amd64.deb
dpkg -i ngcp-rtpengine-iptables_4.1.0.0+0~mr4.1.0.0_amd64.deb
dpkg -i ngcp-rtpengine-dbg_4.1.0.0+0~mr4.1.0.0_amd64.deb
dpkg -i ngcp-rtpengine-dev_4.1.0.0+0~mr4.1.0.0_all.deb

Note: .deb file name may varies with version. 

if you want to install Kernel module then you need to install the dkms package so first install dkms package then install the Kernel module.

apt-get install dkms
dpkg -i ngcp-rtpengine-kernel-dkms_4.1.0.0+0~mr4.1.0.0_all.deb

Now Installation is completed need to run the rtp engine. We need to edit the /etc/default/ngcp-rtpengine-daemon file..

Configuring RTPEngine:

So edit that file to suit your Environment.

RUN_RTPENGINE=yes
LISTEN_TCP=25060
LISTEN_UDP=12222
LISTEN_NG=22222
LISTEN_CLI=9900
INTERFACES=”x.xx.xx.xx”
LOG_LEVEL=6

Running RTPEngine:

Now start the rtpengine using above init script.

/etc/init.d/ngcp-rtpengine-daemon restart
or
rtpengine –interface=192.168.18.20 –listen-ng=127.0.0.1:22222  -m 30000 -M 35000

Check if rtpengine started or not by running below command

ps -ef | grep ngcp-rtpengine

That’s It.. you successfully installed RTPEngine on Debian Ubuntu 14.04. It is ready to accept the requests from Kamailio and Opensips and also configure your kamailio or opensips RTPENGINE_SOCK parameter properly.

If you got any problem, Feel free to drop a comment.
