About Sippy RTPproxy

The Sippy RTPproxy is a high-performance software proxy server for RTP streams that can work together with  SIP Express Router (SER),  OpenSIPS,  Kamailio, Sippy B2BUA or  reSIProcate B2BUA.

The main purpose of RTPproxy originally had been to make the communication between SIP user agents behind NAT(s) (Network Address Translator) possible. Several cases existed when direct end-to-end communication is not possible and RTP streams have to be relayed through another host. The RTPproxy can be used to setup such a relaying host.

Later on it became apparent that there are many other possible uses for this software. It can be used in combination with signalling element (SIP Proxy or SIP B2BUA) to build complex VoIP networks, optimize traffic flow, collect voice quality information and so on. It can perform number of additional functions on RTP streams, including call recording, playing pre-encoded announcements, real-time stream copying and RTP payload reframing.

The RTPproxy supports some advanced features, such as remote control mode, allowing building scalable distributed SIP VoIP networks. The  nathelper module included into the  SIP Express Router (SER),  OpenSIPS or  Kamailio as well Sippy B2BUA allow using multiple RTPproxy instances running on remote machines for fault-tolerance and load-balancing purposes.

RTPproxy was developed by Maxim Sobolev and now is being actively maintained by the  Sippy Software, Inc.

Why RTPproxy?

Traditional PBX-like VoIP switching packages act as a hub, pinning both media and signalling in one place. Such place often becomes bottleneck or single point of failure. In the modern interconnected world handling signalling separately from media in a distributed manner is necessity to build any network of medium or large size.
