The Audrey Caller ID program or ACID, is the killer app for Audrey! It is an extremely well done program that turns on Audrey's screen to display the name and phone number of a caller when the phone rings. Many great options are available with this program such as alert lights, looking up numbers in your Palm database, emailing you when a call comes in and more!  It can even send the caller ID information to other Audreys on your home network through the LAN so only one Audrey needs to be connected to your phone line. It was created by James Mazrimas and more information about this great program can be found here.
