Sets the machine so that the first caller will get 4 rings before the machine answers. If you call in to receive messages from an outside phone and get more than two rings without it picking up, you know there are no messages and can hang up before being charged for a toll call.
Toll saver is an option that lets you know, when you call to retrieve you messages, and hear two rings, that there are no messages. If you hang up right away, there are no toll charges.
In message center mode allows the unit to not answer until 4 rings when no ICM or/and Fax Message is stored and answer on 2 rings when a message is stored.
When you call to retrieve your messages and hear two rings, it means that there are no new messages. Simply hang-up during the second ring and save the toll charges. If there are new messages, you will hear your own greeting pick up after the first ring.
When checking your messages from a remote location, the system will answer on the first ring if you have any new messages. If it doesn't, you can hang up to avoid possible toll charges.
