- Better-than-landline call quality
I'm somewhat of a voice quality nut, though I also give some consideration to the wallet.
If you want much better than landline quality, e.g. to hear your grandchildren almost like you are visiting them, you have to bypass the PSTN. Period. The best phones in the world can't reproduce frequencies higher than 3500 Hz on PSTN calls; this is a limitation of the G.711 codec. An easy way to have wideband voice is to use Skype or similar, with decent headsets on both ends.
Nearly all IP phones sold today have wideband, often called "HD voice". Though getting an HD connection usually requires that your contact have the same provider (and of course an HD phone), these phones also generally perform better on the PSTN, because the mics and earpieces are of higher quality. A cordless IP phone has less quantizing noise; using a cordless POTS phone with an ATA involves needless conversion from digital to analog and back to digital, in each direction. Though not directly related to voice quality, IP phones are free of DTMF and talkoff issues, and usually have better doubletalk performance and fewer echo problems.
Last year, I bought new phones for our winter apartment: two Aastra 6730i corded desk phones, used for most calling, and a Gigaset A580 IP with three handsets, primarily for convenient answering from bed, living room and kitchen. On a higher budget, I would have chosen Polycom and Panasonic. An old SPA3102 allows the Aastra phones to access the local POTS line. My OBi is at another location, providing access to the pseudo-POTS (triple play) line there. (It could also provide access to Google Voice.)
Most good cordless phones sold today (IP or not) use the DECT standard, which operates at 1.9 GHz. A handset should work anywhere in an apartment or smaller home. If you have a big house, put the base near the middle and on a high shelf, away from obstructions, and you will probably be fine. If you have a big yard and want it to work anywhere on your property, putting the base in the attic may work, or you may need a commercial system with multiple bases, e.g. Snom.

My AT&T Dect 6.0 phone works 100s of feet from the house with no problems. Consumer Reports does regular reviews of phones and phone systems. Panasonic usually ranks quite high.
Of course AT&T phones were sold off years ago to a third party and have no connection to AT&T the phone company...

I know my comment is a little off topic but speaking about HD voice: does anyone know
if the Obi HW is able to support any type of HD codec (be it G722, AMR-WB, G711.1 etc) assuming an HD capable
handset is connected to the port ? or is there any info regarding future support plans for such codecs ?
Additionally: assuming that the Obi does not have to do any encoding/transcoding to an HD codec because
an IP phone can do that, will the obi pass on such a codec type in the SIP request/offer?
I have a GS phone which is HD capable and I have it connected through the Obi. In this case
the Obi doesn't even have to do the encoding because the IP phone is capable of doing that.
But the Obi naturally doesn't offer an HD codec even if no voice processing is required.
It would be really interesting to have HD quality even in a limited set of scenarios
where the calls are between Obis or that the Obis are connected to HD capable IP phones.
It would be interesting to know if there is more info or plans on this front.

Well I was thinking that the Obi202 has an USB port. That port, if they wanted could be the connection point for an H.264 webcam making it an audio/video solution. Currently the only others doing that are some expensive TVs with a proprietary camera.
