MediaProxy Features

MediaProxy Feaures

Basic functions

• Basic offer/answer
• Call recording
• Music-on-hold
• Transcoding

Configuration & Management

• Graceful shutdown
• Configurable IP and UDP port range
• Automatic load balancing and redundancy
• Control socket using IPv4/IPv6 UDP/TCP
• Setting internal parameters via HTTP-JSON interface.
• Kamailio-style timeout notifications via IPv4/IPv6 UDP/TCP (configurable)
• JSON command protocol

Media

• Support for any combination of audio and video streams
• WebRTC-style RTP/RTCP muxing/demuxing from/to two independent channels (automatically)
• IPv4/IPv6 bridging for RTP/RTCP
• Video with transcoding.
• Transcoding offloading using dedicated hardware
• kernel based forwarding - It provides better performance than doing it through the daemon, less CPU overhead and lower jitter.

Network

• Multiple networks bridging (more than just three - internal, external, ipv6).
• STUN/TURN/ICE
• SRTP / ZRTP

Accounting and statistics

• Real-time sessions statistics
• RADIUS accounting (start / interim update / stop, configurable)
• JSON stats retrieval via HTTP (queries like http://localhost:8442/json/?callid=0003e30c-c50c0134-763a6f53-359481cc@192.168.0.100&payload=0 - available parameters are - payload, callid, mediaid, tag, remote IP)

Logging

• Events logging (start, stop, interim update, timeout, codec/parser error) to syslog (with full RTCP printing)
