Static heard on all Google Voice calls on OBi202

If you are going to the store to buy a phone for testing anyway, and if you are able to do so temporarily (1 day) on a credit card, why not buy both types of phones just to test? It doesn't have to be expensive...just cordless using those frequencies...a 5.8 and 1.9 GHz.
Another thing you can do, if it is possible, to turn off every single electrical device (temporarily) except your modem and router, and see if that helps your current cordless. If it does, slowly turn on each off device--one at a time--and make calls each time--to see where the culprit is--if it is indeed one of them.
Great suggestions, LTN1, thanks!
I'm having a hard time finding any local stores that carry any decent VTech phones (I'm interested in trying one that has HD Audio), but I'll see what I can find.
Your suggestion to try isolating the device that might be causing the interference (assuming it is interference) is a good one.
What I'd like to do is to exchange the OBi202 for another one, but I'm not sure if OBiTalk will issue a return authorization, if their diagnostic tests on my connection didn't show any problem. I've had it for too long to return it to Amazon.

There are a very large number of people using Panasonic DECT 6.0 cordless phones with OBi products. AFAIK, nobody has reported symptoms like this. In my experience, Panasonic makes very high quality phones. I don't see how switching to Vtech would help at all. "HD Audio" isn't an official/standard term, but it generally refers to the use of wideband audio CODECs on pure VoIP calls (the entire call path is via VoIP, vs. the legacy public switched telephone network, or PSTN). The PSTN is limited to narrowband audio, and the OBi 200 series, designed to be used with standard telephones, doesn't support wideband CODECs. So, a "HD Audio" phone would not necessarily sound better, since it is limited to G.711, although it might have better quality audio amplifiers, microphones, speakers etc.
DECT 6.0 uses a dedicated 1.9GHz radio band, that is not used (well, legally) by any other equipment. Typical wireless devices using WiFi or Bluetooth run on 2.4GHz or 5.8GHz, and as far as home automation goes, I can't speak for the old crap (X-10 or Insteon) causing interference over power lines, but Z-Wave uses the 900MHz band, and Zigbee also uses the 915MHz band, so neither one should interfere with DECT.
I have a very large WiFi network with a large number of devices running on both WiFi bands, and I have a Z-Wave mesh network running about 16 devices, and no interference with my phones.
I gave you some options to explore beyond Google Voice. I suggest testing with a SIP ITSP, such as Callcentric, to compare call quality. Aside from that, if you can't find the problem, all I can suggest is to return the OBi for exchange or refund.
LotharX:
I actually meant to comment on your suggestion earlier to try another VoIP service like Callcentric, Steve, but forgot about it. That is high on my to-do list for tomorrow.
You've just made me re-think my idea to keep testing various cordless phone models, to try to get around the potential interference problem. I've grown weary of running around to local stores looking for other models that might work better. Any halfway-decent-quality cordless phone shouldn't be giving me the problems that I've been experiencing.
That's very useful to know that nobody has reported any issues similar to mine with Panasonic phones. I'd sure rather keep mine, since I can't return it now.
Based on everything that I've been reading about ObiTalk adapters, I'm doubting that their equipment is at fault, unless I just got a defective unit. It happens.

It's a gimmick. I've tried the phone. All "HD Audio" means, in this case, is preset equalizer settings. That's it.
I've tested VTech, AT&T, and Panasonic DECT 6.0 phones. I always return to Panasonic.

That's really useful to know guys, thanks! You just saved me from buying a useless phone tomorrow.
I've been using a Panasonic PBX system for many years, and have always been impressed by it. Different tech, I know, but that company makes quality products.
