Proxy Mailboxes; Amis Node - Toshiba Stratagy IVP8 Installation And Maintenance Manual

AMIS Networking

AMIS Node

The remote system (node 33) receives the message and stores it in mailbox 200.
An exception occurs if the 33200 destination address also exists on the local Stratagy system. The
user must follow the node number with "*" (e.g., 33*200) when entering the destination. This flags
the message as an AMIS message and the Stratagy system delivers the message to Gateway mailbox
33 at Los Angeles instead of Dallas mailbox 33200.

Proxy Mailboxes

The Proxy mailbox represents a specific User ID mailbox on a remote node and resides on the local
Stratagy system. A Stratagy user addresses a message to a Proxy Mailbox in the same manner as
he/she would a local user. Once the message is addressed and sent, the Proxy mailbox initiates the
AMIS transfer. This gives the appearance to the local user that the remote user has a mailbox on the
local system.
For example, assume User ID mailbox 2300 is a mailbox on a voice mail system in Dallas. The same
number also resides as a Proxy mailbox on the local Stratagy. When messages are left for Proxy
mailbox 2300 on Stratagy, the system uses the information stored there to contact the Dallas voice
mail system, provides some handshake signals requesting User ID mailbox 2300, then audibly
transmits the message. The Dallas voice mail system would receive the message and store it in User
mailbox 2300.
Important!
AMIS Node
An AMIS node is a voice mail system in an AMIS network. Each node in the network is identified
in two ways. First, there is a unique node number (the box number of the Gateway mailbox) that
must be used as part of the message address when sending, forwarding or replying to a message.
Second, the nodes use the System Identification Number, which is part of the AMIS protocol, to
identify themselves to each other during AMIS connections.
As more advanced features have been added to the DOS®-based Stratagy systems, memory
management has become a critical issue in software development. Because of this, TAIS/TSD
looks toward feature interaction as a way to create more operating system memory when
developing new features. With the addition of the Call Record feature to the DOS-based products
with Release 3.3 software, the number of default Audio Messaging Interchange Specification
AMIS) networking nodes has been reduced to 200. In addition, further restriction to the number of
(
AMIS networking nodes will be required to support IVP8 systems with multi-lingual prompts.
The fewer AMIS nodes the system is configured for, the more operating system memory is
available for other features. The Stratagy systems reserve enough operating system memory to run
the number of AMIS nodes specified in the amis_max_nodes parameter in the Stratagy System
Configuration. Additionally, a system using more features and a higher configuration requires
more operating system memory. For example, an eight port IVP8 system with a high amount of
call traffic using the new Call Record feature requires more operating system memory than a
system with fewer ports and/or less traffic. Multi-lingual prompts have been specifically identified
as a feature that requires a reduction in the number of AMIS nodes to increase Operating System
(OS) memory for proper system operation.
Due to the number of feature configurations possible in a Stratagy system, it is not possible for
TAIS/TSD to accurately identify the correct number of AMIS nodes in each case. If the system
you are working on runs out of OS memory, the failure causes the system to continually reboot. To
correct this, the number of AMIS nodes must be reduced.

It is not necessary for the remote mailbox number to match the Proxy mailbox
number in Stratagy.
