Need new land line phone for business

[DharmaDog]

I have an AT&T phone that I like, but I need to go wireless.

I work in a home office and sometimes am in another part of the house when the phone rings and the only phone is in the office.

The wireless phone must be able to get exceptional reception because I'm frequently on conference calls. It also must have a good speakerphone capability in the handset and headset support, preferably using 1/8" phone plug. Oh, and I'd like a minimum of two handsets in the package.

Any recommendations?

Thanks
