Forward audio data from a SIP call to remote TCP port

[Yury Pogrebnyak]

I know WCS can forward audio from a SIP call to a RTMP server. Does it also allow to forward audio data directly to an open remote TCP port? Or alternatively send it over websockets?

Even if you receive audio over TCP, you will not be able to play or record these packets properly, because you need a transport protocol like RTMP or RTP providing at least sequence numbers and timestamps. Of course it can be own implemented protocol similar with RTP.

Does it also allow to forward audio data directly to an open remote TCP port?

No. It is not currently supported.

Only option, you can connect to WCS over TCP/RTSP and try to fetch this stream over TCP/RTSP/RTP (interleaved mode).
So you need an RTSP client like VLC player that connects to server and receives RTSP/RTP audio traffic over TCP in G.711 codec.

How do I find this stream over TCP/RTSP? Do you mean when I initiate a call via WCS the stream can be somehow accessed remotely?

Yes. Please checkout previous post related call to stream mapping:
https://forum.flashphoner.com/threads/capturing-raw-audio-data-from-a-sip-call.11083/#post-13877
You can map a call to stream and set unique stream name for this stream.
Then the stream will be accessed remotely by streamName.
It should be accessed by all protocols supported in WCS, including RTMP and RTSP.

rtsp://host:554/stream1
Here stream1 is name of mapped stream.
