There is a reason why Polycom isn't a public company any more ;)

I'm in the moving away from hardware codecs camp as well. Unless the client already has legacy systems or specific far ends to connect to that have them or is looking for the best of the best (hardware, but not Polycom), most clients will be much happier with a software based system; Skype4B, Zoom, and WebEx being the most popular in my experience.

Polycom is one of the few DSPs that doesn't include USB today natively just for that reason (their DSP line is like 10 years old. albeit rock solid reliable for what it is), but it can be adapted fairly easily. For smaller rooms, the Trio 8800/8500 work great as a SIP phone/USB audio interface. Tabletop SIP phones are most of Polycom's revenue now, particularly Skype4B phones. The rest of the market has kind of passed them by in their efforts to Make the VC Market Great Again rather than keeping up with the changing world.

Lots of other audio options for smaller rooms if you don't want the SIP phone in the same box, but that way looks nice and keeps the table clutter to a minimum (Revolabs/Yamaha UC, AcousticMagic, Jabra, etc.).

You can use any camera with an external USB encoder or there are tons of USB cameras available now. Vaddio, Marshall, Panacast, HuddleCam, VDO360, ClearOne, Logitech, etc., etc.
