Re: Stream audio to Speech to Text engine

Thanks Andreas,

the Python bindings have the same API as the PJSUA2 C++ library. But still the C API is even more low level so maybe I will need to use it instead of the Python :(

You described it correctly. My APP receives the call, negotiates via SDP and then should redirect the incoming RTP stream to STT engine. After the call end, the app should close the RTP stream in the STT engine and that all.

I checked the resources for you and I think you are right that modification of the SDP is not a good idea. Also, after reading the resources and references I found this Still I think it's overkill to implement new port to just pass the traffic to another app. I would like to somehow hook into the PJSUA2 initialization and instead of creating new RTP socket in PJSUA2, I want to simply create it in the STT engine and provide opened port to PJSUA2 instead. This RTP stream will be redirected and PJSUA2 don't need to know about it.

The steps you provided helped me understand the PJSIP in more detail, but unfortunately I still don't understand what do you suggest. Creating the streams and registering them to conf. bridge is done automatically in PJSUA2 and I am not sure if you suggest to create extra stream for RTP and conf. bridge will be kind of proxy were RTP will go from one stream to another. Do I understand it correctly or is it something else?

Thanks in advance for the clarification and have a nice day :)
