Does 501 caller id feature have call waiting id? If you are on the phone and you hear a beep will it show up who is calling you on that beep before accepting that beep? If not will it show who is calling when you accept the beep? There are caller id's that have the call waiting id feature where you can see who is calling you when someone is beeping you on the call waiting feature.

I have not seen docs on this, but it seems if it DID exist as a feature it would have been announced.
I know mine certainly has not ever responded to and CWCid...

I just tried it. Nope, the 501 does not display call waiting ID data.
