How will it function/work?

With TeleMail or any answering device; a message will be deposited in your mailbox or saved on any answering device on the first day and you will not be notified again.
No TeleMail or any answering device; your telephone will ring on the 1 st day during given timeslots. If not picked up, the system will call again the next day at the same timeslots; if not picked up on the 2nd day the system will call again on the 3rd day and if not picked up then the message will expire automatically.
When you answer your phone; the system registers a successful call and does not remind you again, provided that you have listened to the full message.
