Start rtp without sessioning protocol

Question

Is it possible to have one way streaming via RTP without the initiation of an RTP session via SIP or some other protocol?

In other words, if a streaming source just starts sending RTP packets, can they be interpreted by the destination if no sessions have been initialized prior the sending?

Answer 1

Yes, it can. But there have to be many preset parameters:

1. Ip and ports used.
2. Codecs used.

3. Codec configuration parameters

   ...

And, of course, you have to make sure that the receptor is ready to accept the packets sent, etc.

In other words: you can, but you should take care of all those things that SIP, RTSP, or other protocols do when setting up a multimedia session.
