RTP.IO module
Admin Guide
Section titled “Admin Guide”Overview
Section titled “Overview”The RTP.io module provides an integrated solution for handling RTP traffic within OpenSIPS, enabling RTP relaying and processing directly inside the OpenSIPS process. This eliminates the need for external processes such as RTPProxy, resulting in a more streamlined, efficient, and manageable system for certain use cases.
The rtp.io module starts RTP handling threads in the main OpenSIPS process and allows the rtpproxy module to access these threads via a one-to-one socket pair. This tight integration facilitates efficient RTP traffic management within OpenSIPS without relying on external RTP handling services.
The module requires RTPProxy version 3.1 or higher, compiled
with the --enable-librtpproxy option to build. It utilizes the
librtpproxy library to manage RTP traffic and interfaces with the
existing rtpproxy module to generate commands, parse responses,
and process SIP messages.
When the rtpproxy module is loaded without arguments and the
rtp.io module is also loaded, the sockets exported by
rtp.io are used automatically in set 0.
Alternatively, these sockets can be incorporated into other sets by using the
"rtp.io:auto" moniker.
