[pulseaudio-discuss] How to implement CS-call module in PA?

[tieg]

Hi, all:

I'd like to implement a CS-Call module in pule audio. That is to say
voice call data will be handled at user space. Such mechanism is
different from traditional H/W voice call solution. Its pros points is
voice data can be rendered specially. For example, you can add
echo/noise cancellation.

Is there any examples or guide I can refer to?
