I am not a speakerphone user myself, and most of our customers are not.
 Every now and then we get one that doesn't like the SPA phones, and
probably wouldn't like the Grandstream either.  We give them a Polycom.

The Grandstreams from a few years ago gave us a lot of issues on SIP and
provisioning, but that's gone as far as we've seen.  I originally turned
down the offer of some demo phones based on past experience, so I urge
everyone to discard that experience and see it as a new product.

Yeah, I'd never use speakerphone when talking to anyone, so user type will
be important here.  I always recommend a headset to the speakerphone users,
about 50% go for it.
