Yeah. And high fidelity sync between audio (ideally via phone). Maybe someone does it, but we tried _all_ vendors and settled on Zoom. And screen annotations, and the ability to remember participants' phones and dial them directly (replaces them having to type 9 digit numbers into their phones), etc.

Also, Zoom has reached a critical mass where, particularly for sales calls, the remote party is quite likely to have it installed. The network effect here is really valuable.
