When I call from cell phone to the cordless, I can hear ringing in the cell phone. I can pick the non-ringing cordless and talk normally. The connection is good as normal, only problem is I do not get notification of an incoming call.

[TELECOM Digest Editor's Note: But when you unplug your cordless phones and replug them in at someone else's jack they _always_ work correctly? (yes/no) You have two cordless phones now, the original one plus a new one you bought recently? Do they both always work OK at the other location while _NOT_ working at your location? (yes/no) At your place, knowing that a call is coming in (your own cell phone) you can answer all incoming calls without having heard a ring? (yes/no). The phones work okay at both locations except you do not get a ringing signal (although you know it is 'ringing' at your place?) If for all these questions your answer is (yes) then I strongly suggest the hassle is somehow with your own wiring. PAT]
