Once the message has been sent, voice mail dials the remote Destination System Number. The 
message is placed in the remote mailbox and the user is returned to the Main Menu. If the 
transmission fails, voice mail retries up to nine times before returning the message back to the user 
for one of the following reasons:

Remote node does not answer

Remote node is busy

Message is too long

Node’s phone number is incorrect

Mailbox number does not exist

Mailbox not accepting messages

Mailbox is full

Protocol error

Because AMIS does not support Special Delivery Options, the voice mail proprietary options such 
as “private” or “urgent” are striped off when the message is sent via AMIS. These messages at the 
receiving mailbox are handled as normal messages.

However by using the Notify record, voice mail can use the “urgent” option to determine the timing 
of the AMIS transmission. For example, normal messages can be delivered after 5:00 p.m. and the 
urgent messages immediately.

Each remote node is represented by a Gateway mailbox in the local node. The node number is the 
mailbox number. When a message is addressed to a remote node, it is placed in the Gateway 
mailbox, with information in its header that identifies the remote box number, and the fact that it is 
an AMIS-deliverable message.

A notify task is started to deliver messages to the remote site. There can be several notification tasks 
for a Gateway mailbox. For each notification task, a maximum of nine messages can be transmitted. 
The number of messages that can be stored in the Gateway mailbox is set by the system maximum.

If a notify task was started as the result of an urgent message being placed in the Gateway mailbox, 
it is only allowed to deliver the urgent message to the remote node. The urgent status is stripped 
from the message when it is sent.
