In AMIS terminology, Cisco Unity and the other voice messaging systems that it communicates with are

called nodes. Each node is assigned a unique ID, referred to as a Node ID. The node that places an AMIS

call and delivers messages is called the originating node. The node that answers the AMIS call and

receives messages is called the destination node. If a particular system acts as both an originating node

and a destination node, its Node ID is the same for both functions. AMIS nodes correspond to locations

in Cisco Unity.

The Cisco Unity subscribers and the users on the other voice messaging systems are identified by

mailbox numbers. On Cisco Unity, the mailbox number for a subscriber is the same as the subscriber

extension.

Voice messages are transmitted between nodes by using ordinary phone connections. When one node

calls another by dialing a specified delivery phone number, the originating node transmits its Node ID

by using a sequence of touchtones. If the destination node accepts the call, the originating node transmits

each voice message by using analog playback, and the destination node records each message and

delivers it to the applicable mailbox. For detailed information about the touchtones that are transmitted

during an AMIS call, see the AMIS Analog Networking Definitions white paper, at
