Another article on installations. To test media relays I have to install SIPP. It is actually a bit tricky.

apt update
apt install git pkg-config dh-autoreconf ncurses-dev build-essential libssl-dev libpcap-dev libncurses5-dev libsctp-dev lksctp-tools cmake
git clone https://github.com/SIPp/sipp.git
cd sipp
git checkout v3.7.0
git submodule init
git submodule update
./build.sh --common
cmake . -DUSE_SSL=1 -DUSE_SCTP=0 -DUSE_PCAP=1 -DUSE_GSL=1
make all
make install

Verify by using the command below

sipp -v
