iPhone Paired with Bluetooth Telephone

I've got the ATT TL92278 it seemed to work fine for a while but then I realized it was constantly forgetting the pairing. I thought it was the ATT home phone's problem till I started searching the apple forums.

It seems the iPhone has a really poor ability to maintain a pairing with 3rd party hardware including my ATT bluetooth home phone and though the issue is several months old, there doesn't seem to be a fix yet.

I'd say hold off on doing this for a while because right now I have to unpair and re-pair the phone everytime I leave home with my iPhone and return now. From the issues other folks are having with their cars, headsets, computers, etc. with maintaining a pairing I'd say you're likely to have this problem with the v-tech or panasonic bluetooth phones as well.

i also can't keep the units paired. I thought turning the Iphone off and on was a fix. Not correct.
When it works, its great.
I also had a Panasonic model and it held the pair longer, but still would lose it.

If you read the reviews of the AT&T bluetooth phone system at BestBuy.com or Amazon, you'll find that the system is working perfectly for non-iPhone users - no issues with the pairing not "sticking". The problem indeed seems to be with bluetooth on the iPhone.

I'm sure Apple is aware of this and other bluetooth issues on the iPhone, but they'll probably come out their own "iVOIP" phone system that seamlessly integrates with the iPhone and iPod touch. And it'll probably cost $400.

We bought a VTech S5145 (http://www.vtechphones.com/vtechui/store/dsp_product.cfm?itemID=3676&parent=2306 8) in December, and we are having the same problem. Good to know its the iPhone and not the VTech ... at least I have some hope for a firmware upgrade to resolve the issue.

Does anyone know if OS 3.0 solves this problem? I am determined to drop my landline and prefer an iPhone, but I need several handsets in the house and can't deal with the pairing problem as described here (and elsewhere).
