Hello Alexei, PJmedia through Portaudio does not suport addition or removal of audio devices on the fly. If you use a Mac you can try what we did to support this that works fine in Blink: http://sipsimpleclient.com/ticket/75 You need to patch both portaudio and pjsip to make it work correctly. Also read though the ticket for how to work around the multithreading issues in your client.
