Hi Per, Pjsip just supports WinMME and PortAudio on Windows, but PortAudio supports DirectSound. I don't know of any ASIO drivers for pjsip, you could certainly write one. There's various places you could wire in. As I mentioned earlier you could do it in the conference mixer. You could directly modify the mme driver and stick it in there, or you could use pjmedia_port interface to wire it up in between conference mixer and sound device. I would study the chain from the conference mixer outbound to the device. Bill On 10/30/2014 6:16 PM, Per Cramer wrote: > > Hi Bill (and others), > > > does pjsip use port audio also on windows?
