Hi all, I'm having issues with a constant level of background noise on the PJSip conference bridge. It sounds like a gentle hissing or static sound, and it's constant regardless of whether people are talking or not. If I create a simple app to test the mic/speaker independent from PJSip then no hissing is heard, pointing to a software issue. Is there some sort of comfort noise generator that I might have missed? Or is there some other explanation for why this noise is being generated? Thanks for any help/pointers. I've been scratching my head over this one for days. Dave
