Hi David! I can definitely update you on the VOIP phones. Well, we fiddled around more with ADA's and stuff and still couldn't get the results we wanted, so we decided to break down and get an IP phone with DECT 6 handsets. We chose the Snom M9 since our VOIP provider recommended it, and we knew we could get everything working perfectly with it. Found it on Amazon for about $270 total, which included 3 handsets and the shipping charges to ship from a couple locations. One of the handets and the base station arrived last week, and the rest should be arriving this week. Still took a few hours on the phone with RingCentral support to get the Snom M9 functioning on their setup (since the instructions on their website were completely wrong), but once we got the base station configured, everything kicked in and we've had a great working phone with all the features. Still learning how to use it, and we're tweaking sound settings and stuff as we go with it, but so far so good. When the other handsets arrive, I should be able to just pair them up with the base station and keep on going. It was a little more costly than using an ADA with a regular phone, but we are getting excellent sound quality, the features "just work" without fiddling around a bunch of settings, the quality of the phone itself is pretty solid and, the phone is very easy to use, and I can eBay all my current phones and send back the ADA's and equipment and it not be too costly for us.
