I have a customer with an AT&T Spirit 308. They want "voicemail" or "telephone recorder". My looking thus far indicates get the local telephone company voicemail. Any thoughts?

Take line one loop it to an answering maching and have them turn is on at night or set the rings to enough to auto answer. Done that a zillion times.

Sell them a newer system that is voice mail compatible. cha-ching $$

Thanks for the information. Where's my head? I should have thought of putting the unit ahead of the KSU! Thanks a lot!
