Example: Similarities and Limitations of
Cisco Unity Messaging vs. VPIM Messaging
• Marked urgent = Retrieved urgent
• Marked private = Retrieved private
• Read and delivery receipts = Delivery receipts
• E-mail without voice attachment = Rejected

What Are the Options for VPIM Addressing?
Options for VPIM addressing:
• VPIM subscriber (names, extensions)
• Blind addressing

Example: Address by Name
[email protected]
Standard SMTP Address

CUDN v1.1—4-6
Example: Blind Addressing and VPIM
Networking
• Information about the address does not exist, so: Blindly
send the message to the dial ID in the delivery address.

Addressing
433 5654
To get the message to Joseph,
Jessica has to add the location
dial ID to the message.
Location 433
The actual message sent to the other Cisco Unity will look like:
[VPIM:<Delivery Location Dial ID>_<Remote Mailbox Number>]

Example: How Cisco Unity Voice Connector or Interop
Gateway Processes Outgoing VPIM Messages
• Constructs To address
• Hands off to Exchange and Cisco Unity Voice Connector
– Converts message to MIME
– Formats To address
– Formats From address
– Converts to G.726
– Attaches recorded name or vCard
• Puts out for delivery

Example: How Cisco Unity Voice Connector or Interop
Gateway Processes Incoming VPIM Messages
• Verifies from delivery location
• Removes phone prefix
• Validates recipients
• Converts to MAPI
• Converts voice to specified codec
• Hands message back for delivery

What Are VPIM Subscribers?
Cisco Unity tracks which subscribers
are local and which are VPIM.
VPIM
• VPIM subscribers can be created
with the System Admin tool one at
a time.
• Use the bulk import tool to
create VPIM Subscriber in bulk.
• Cisco Unity can be set to create
VPIM subscribers automatically
when a VPIM message is received.

CUDN v1.1—4-13
Example: Subscriber Experience with VPIM
Subscribers
• Address messages via phone
• Listed in address book
• Voice name confirmation
• Part of distribution lists

Creating VPIM Subscriber Creates
Extension Address
• Creating a VPIM subscriber creates an e-mail
address from the location and remote mailbox
number. The @Companyname.com is added
from the Delivery Location page with dial ID 433.

Summary
• When designing a VPIM network, you must define a number
of parameters. They include addressing considerations,
Cisco Unity Voice Connector placement, locations, and how
subscribers will address messages to VPIM destinations.
• A VPIM message is a segmented message containing
message header, voice message, source voice name,
and possibly other fields such as a vCard.
• Messages to a VPIM destination may be addressed either via
blind addressing or by creating VPIM subscribers that point
to the corresponding voice-mail servers.

Summary (Cont.)
• There are two types of locations used in VPIM: primary
locations that identify the local server and delivery locations
that identify remote VPIM destinations.
• The Cisco Unity Voice Connector is used as a gateway to
convert the SMTP message to a MIME message and then
forward it to the VPIM destination.
• The VPIM subscriber has some limitations but overall is
capable of performing most tasks that a Cisco Unity
subscriber can perform.
