phone number lookup for missed phone calls and recordkeeping

[John Murphy]

I get phone calls and if I am in bed asleep at 9 PM and I don't answer they don't leave a message and I would like to find a way online to obtain their info: name, address, etc.

A second question is I receive phone calls when I am running a saw and I may or may not answer but I don't have a good system for keeping records of who called etc.

I talked to someone the other day who told me they sometimes receive 100 phone calls a day, and, like me, they don't carry a notebook around to take the person's name and phone number etc

What's your system for this?

Thanks for any input!
