It's meant to be used with the [Kamailio SIP proxy](http://www.kamailio.org/)\nand forms a drop-in replacement for any of the other available RTP and media\nproxies.\n\nCurrently the only supported platform is GNU/Linux.\n\n## Mailing List\n\nFor general questions, discussion, requests for support, and community chat,\njoin our [mailing list](https://rtpengine.com/mailing-list). Please do not use\nthe Github issue tracker for this purpose.\n\n## Features\n\n* Media traffic running over either IPv4 or IPv6\n* Bridging between IPv4 and IPv6 user agents\n* Bridging between different IP networks or interfaces\n* TOS/QoS field setting\n* Customizable port range\n* Multi-threaded\n* Advertising different addresses for operation behind NAT\n* In-kernel packet forwarding for low-latency and low-CPU performance\n* Automatic fallback to normal userspace operation if kernel module is unavailable\n* Support for *Kamailio*'s *rtpproxy* module\n* Legacy support for old *OpenSER* *mediaproxy* module\n* HTTP, HTTPS, and WebSocket (WS and WSS) interfaces\n\nWhen used through the *rtpengine* module (or its older counterpart called *rtpproxy-ng*),\nthe following additional features are available:\n\n- Full SDP parsing and rewriting\n- Supports non-standard RTCP ports (RFC 3605)\n- ICE (RFC 5245) support:\n  + Bridging between ICE-enabled and ICE-unaware user agents\n  + Optionally acting only as additional ICE relay/candidate\n  + Optionally forcing relay of media streams by removing other ICE candidates\n  + Optionally act as an \"ICE lite\" peer only\n- SRTP (RFC 3711) support:\n  + Support for SDES (RFC 4568) and DTLS-SRTP (RFC 5764)\n  + AES-CM and AES-F8 ciphers, both in userspace and in kernel\n  + HMAC-SHA1 packet authentication\n  + Bridging between RTP and SRTP user agents\n  + Opportunistic SRTP (RFC 8643)\n  + Legacy non-RFC (dual `m=` line) best-effort SRTP\n  + AES-GCM Authenticated Encryption (AEAD) (RFC 7714)\n  + `a=tls-id` as per RFC 8842\n- Support for RTCP profile with feedback extensions (RTP/AVPF, RFC 4585 and 5124)\n- Arbitrary bridging between any of the supported RTP profiles (RTP/AVP, RTP/AVPF,\n  RTP/SAVP, RTP/SAVPF)\n- RTP/RTCP multiplexing (RFC 5761) and demultiplexing\n- Breaking of BUNDLE'd media streams (draft-ietf-mmusic-sdp-bundle-negotiation)\n- Recording of media streams, decrypted if possible\n- Transcoding and repacketization\n- Transcoding between RFC 2833/4733 DTMF event packets and in-band DTMF tones (and vice versa)\n- Injection of DTMF events or PCM DTMF tones into running audio streams\n- Playback of pre-recorded streams/announcements\n- Transcoding between T.38 and PCM (G.711 or other audio codecs)\n- Silence detection and comfort noise (RFC 3389) payloads\n* Media forking\n* Publish/subscribe mechanism for N-to-N media forwarding\n\nThere is also limited support for *rtpengine* to be used as a drop-in\nreplacement for *Janus* using the native Janus control protocol (see below).\n\n*Rtpengine* does not (yet) support:\n\n* ZRTP, although ZRTP passes through *rtpengine* just fine\n\n## Documentation\n\nCheck our general documentation here:\n* [Read-the-Docs](https://rtpengine.readthedocs.io/en/latest/)\n\nFor quick access, documentation for usage:\n* [Compiling and Installing](https://rtpengine.readthedocs.io/en/latest/compiling_and_installing.html)\n* [Usage](https://rtpengine.readthedocs.io/en/latest/usage.html)\n* [Transcoding](https://rtpengine.readthedocs.io/en/latest/transcoding.html)\n* [Call recording](https://rtpengine.readthedocs.io/en/latest/call_recording.html)\n* [The NG Control Protocol](https://rtpengine.readthedocs.io/en/latest/ng_control_protocol.html)\n* [The TCP-NG Control Protocol](https://rtpengine.readthedocs.io/en/latest/tcpng_control_protocol.html)\n* [HTTP/WebSocket support](https://rtpengine.readthedocs.io/en/latest/http_websocket_support.html)\n* [Janus Interface and Replacement Functionality](https://rtpengine.readthedocs.io/en/latest/janus_interface_and_replacement.html)\n\nFor quick access, documentation for development:\n* [Architecture Overview](https://rtpengine.readthedocs.io/en/latest/architecture.html)\n* [Unit-tests](https://rtpengine.readthedocs.io/en/latest/tests.html)\n* [Troubleshooting Overview](https://rtpengine.readthedocs.io/en/latest/troubleshooting.html)\n* [Glossary](https://rtpengine.readthedocs.io/en/latest/glossary.html)\n\n## Sponsors\n\n* [Dataport AöR](https://www.dataport.de/)\n\n## Contribution\n\nEvery bit matters.
