rtpengine having Debian as a target platform. But sometimes you need Red Hat-based distros.
This guide documents the steps to compile and install rtpengine version mr13.5.1.3 (and I guess all 13.5.x branch) on a plain RHEL 9 system.
Enable Required Repositories
sudo dnf -y install epel-release
sudo dnf -y update
Install Development Tools
sudo dnf -y groupinstall "Development Tools"
sudo dnf -y groupinstall "RPM Development Tools"
Install Build Dependencies
sudo dnf -y install \
gcc \
make \
pkgconfig \
redhat-rpm-config \
glib2-devel \

Install FFmpeg
sudo dnf -y install ffmpeg-free-devel
Note: you can use ffmpeg-devel from RPM-Fusion repo
Install MariaDB Development Files
sudo dnf -y install mariadb-devel mariadb-connector-c-devel
Create mysqlclient.pc symlink (rtpengine looks for this)
sudo ln -sf /usr/lib64/pkgconfig/mariadb.pc /usr/lib64/pkgconfig/mysqlclient.pc
Install Kernel Development Packages (for kernel module)
sudo dnf -y install kernel-devel kernel-headers elfutils-libelf-devel
Create Stub libiptc.pc File
RHEL 9 doesn't provide libiptc via pkg-config. Create a stub file:
sudo tee /usr/lib64/pkgconfig/libiptc.pc << 'EOF'
prefix=/usr
exec_prefix=${prefix}
libdir=${exec_prefix}/lib64
includedir=${prefix}/include
Name: libiptc
Description: Stub libiptc for RHEL 9 (iptables chain management disabled)
Version: 1.8.9
Cflags:
Libs:
EOF
Verify it works
pkg-config --exists libiptc && echo "libiptc.pc created successfully"
Build and Install spandsp from FreeSWITCH Fork
The standard spandsp package doesn't work correctly on RHEL 9. Use the FreeSWITCH fork:
cd /usr/src
sudo git clone https://github.com/freeswitch/spandsp.git
cd spandsp
sudo ./bootstrap.sh
sudo ./configure --prefix=/usr
sudo make -j$(nproc)
sudo make install
sudo ldconfig
Build rtpengine and it's components
cd /usr/src
sudo wget -O rtpengine-mr13.5.1.3.tar.gz \
https://github.com/sipwise/rtpengine/archive/refs/tags/mr13.5.1.3.tar.gz
sudo tar xzf rtpengine-mr13.5.1.3.tar.gz
sudo mv rtpengine-mr13.5.1.3 rtpengine
cd rtpengine
Build rtpengine Daemon
cd /usr/src/rtpengine/daemon
sudo make RTPENGINE_VERSION=mr13.5.1.3 -j$(nproc) with_iptables_option=no
Build Recording Daemon
cd /usr/src/rtpengine/recording-daemon
sudo make RTPENGINE_VERSION=mr13.5.1.3 -j$(nproc) with_iptables_option=no
Build Kernel Module (Optional)
cd /usr/src/rtpengine/kernel-module
KERNEL_VERSION=$(uname -r)
sudo make RTPENGINE_VERSION=mr13.5.1.3 KSRC=/usr/src/kernels/$KERNEL_VERSION
sudo make install
sudo depmod -a
Install rtpengine
cd /usr/src/rtpengine/daemon
sudo make install with_iptables_option=no
cd /usr/src/rtpengine/recording-daemon
sudo make install with_iptables_option=no
Create rtpengine User and Directories
sudo useradd -r -s /sbin/nologin rtpengine
sudo mkdir -p /var/run/rtpengine
sudo mkdir -p /var/spool/rtpengine
sudo mkdir -p /etc/rtpengine
sudo chown rtpengine:rtpengine /var/run/rtpengine /var/spool/rtpengine
Systemd integration
sudo tee /etc/rtpengine/rtpengine.conf << 'EOF'

port-min = 10000

Configure Firewall (if applicable)
sudo firewall-cmd --permanent --add-port=10000-20000/udp
sudo firewall-cmd --permanent --add-port=2223/udp
sudo firewall-cmd --reload
Load Kernel Module (if built)
sudo modprobe xt_RTPENGINE
Verify it's loaded
lsmod | grep xt_RTPENGINE
To load on boot, create a modules-load.d file
echo "xt_RTPENGINE" | sudo tee /etc/modules-load.d/rtpengine.conf
Start rtpengine
sudo systemctl enable rtpengine
sudo systemctl start rtpengine
sudo systemctl status rtpengine
rtpengine --version
Verification
ss -ulnp | grep 2223
Test with rtpengine-ctl (if available)
echo "list totals" | nc -u 127.0.0.1 222
