Description

This module installs, configure and manages Sipwise NGCP rtpengine.

The Sipwise NGCP rtpengine is a proxy for RTP traffic and other UDP based media traffic. It's meant to be used with the Kamailio or OpenSIPS SIP proxy and forms a drop-in replacement for any of the other available RTP and media proxies.

For more information please refer to the project repository: https://github.com/sipwise/rtpengine

This module affects the following:

  • Adds yum repositories for dependencies
  • Installs rtpengine and dependencies packages
