Nortel's "Maestro" product line includes cordless phones. I've had 2 of those and they are very good. I still use one of their (corded) Meridian phones in my computer room.

Here's info on the Maestro 900 DSS.

I've owned the 900 DSS as well as the Maestro 4600. Both were very good. Back when I worked for Southwestern Bell (*cringe*), we got good deals on Northern Telecom products. :-)
