Chapter 1 Networking in Cisco Unity
Comparison of AMIS, Bridge, and VPIM Networking
Tab l e 1-13 Mailbox ID Translation
AMIS Bridge VPIM
Not available. Prefixes can be defined so that
Cisco Unity subscribers can address
messages to Octel subscribers by entering
a network address consistent with phone
network dial plans.
All Cisco Unity subscribers are mapped
to a configurable mailbox and serial
number value for use when
communicating with Octel servers. This
allows any Cisco Unity subscriber to
represent mailbox X at node serial
number Y within the Octel network,
independent of the Cisco Unity
numbering plan.
Additional digits can be automatically
added to the beginning of the mailbox
numbers that are associated with the
Cisco Unity sender and remote recipient
on messages that are sent from
Cisco Unity subscribers. The same digits
can be removed from the beginning of the
remote sender and Cisco Unity mailbox
numbers for delivery to Cisco Unity
subscribers.
Tab l e 1-14 Fax Messaging
AMIS Bridge VPIM
The AMIS protocol does not support
this functionality.
Supported. Supported; however, VPIM supports only
the TIFF-F message format.
Tab l e 1-15 Message Transport Time Considerations
AMIS Bridge VPIM
Analog delivery of the message from
the sending system to the receiving
system is the most significant
contribution to transport time.
The minimum analog delivery time
can be calculated by multiplying the
actual recording length of the
message by the number of recipients
of the message. The AMIS protocol
requires a separate analog
transmission of the message for each
recipient.
For example, a five-minute message
with 10 recipients would require a
minimum of 50 minutes for the
analog transmission.
Analog delivery of the message from the
sending system to the receiving system is
the most significant contribution to
transport time.
The minimum analog delivery time is the
actual recording length of the message.
Octel Analog Networking allows a single
analog transmission of a message
addressed to multiple recipients, which
the receiving node will deliver to all
intended recipients.
For example, a five-minute message with
10 recipients would require a minimum of
5 minutes for the analog transmission.
Exchange routing time and SMTP
delivery time to a remote VPIM system
are the only considerations.
For example, a five-minute message with
10 recipients would likely take less than
one minute to transmit.
