Unity AMIS-A Networking License, 1 User - UNITY-AMIS
Cisco Unity supports the Audio Messaging Interchange Specification analog (AMIS-a) protocol, which provides a mechanism for transferring voice messages between different voice messaging systems. 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 appropriate mailbox. In compliance with the AMIS protocol, Cisco Unity batches outgoing messages by node, with a maximum of nine messages per batch. If there are more than nine messages for a particular node, Cisco Unity ends the AMIS session after sending the ninth message, hangs up for a brief period of time, and then redials the node to send the next batch of messages. The AMIS protocol specifies that a message be a maximum of eight minutes long. During an AMIS transmission, before playing a message, the originating node sends the destination node the length of the message. If the message is too long, the destination node may refuse the message and skip to the next message. However, some voice messaging systems will accept longer messages. Whether the long message is accepted or not depends on the destination voice messaging system. If the voice messaging system refuses the message, a non-delivery receipt (NDR) is returned to the sender. If a subscriber sends a message that is longer than eight minutes, Cisco Unity will attempt to transmit it. In addition, Cisco Unity may accept messages longer than eight minutes. For each incoming message, Cisco Unity checks the space available in the subscriber mailbox and the Maximum Message Length setting on the Subscriber > Messages page to determine whether to accept the message. Incoming AMIS messages are delivered to subscriber extensions only, and cannot be delivered to public distribution lists.
