I have no clue thats a hard 1

I made one myself, it is easy and you can do it also. Go to an electronics store (I used Radio Shack) and get one of those devices that allow you to record your own telephone conversations on a cassette recorder, hook it in tandem to your answering machine and you have it, you can save/record all messages/conversations on tapes for as long as you want (90 min tapes work best) or re-record over them. The law states that at least one of the people using the phone at the time must be aware that their conversation is being recorded, an answering machine that acknowledges the message is being recorded will suffice for incoming messages to a phone that is being answered by a machine. As for recording conversations between two people that have no idea their conversation is being recorded you may violate existing laws against wire taps/invasion of privacy. Nye
