Same here. That is why my wife's office is on a main floor of the house and mine is in the basement. She's been remote for at least 10 years I think and I ran my own product development business since 2000.
its only an issue for my girlfriend and I when we're both on calls at the same time. I use a wireless 2.4Ghz headset so I can go outside on the patio - solves the issue nicely :-)
