RTPengine is a highly efficient and versatile media proxy that enables telecommunication and VoIP providers to handle real-time media streams in a scalable and flexible manner. Whether you need to proxy media streams between endpoints, record media streams, or manipulate them in some other way, RTPengine provides the tools you need to get the job done. In this post we will show how to install it on Debian 11. This OS version relies on nftables rather than iptables and rtpengine relies on iptables. Thus it is required to remove nftables and a add iptables back.

apt-get remove --auto-remove nftables
apt-get purge nftables
apt-get update

Now install iptables

apt-get install iptables-persistent iptables

Install the packages required to clone the repository

apt-get gnupg gnupg2 git mc
