Hi, I am currently trying to figure out the easiest way for an application to associate a call with an audio device. It seems as if pjsua_set_snd_dev() would be the function to use, but I wonder whether that function changes the sound device for all calls instead of just a particular one? Is pjsua even suitable for handling multiple distinct calls at the same time, or do I need to use lower-level calls for that? Any pointers would be greatly appreciated! Thanks, Hans
