Overview of Cisco Unity Express Networking
• Spoken name confirmation
Blind Addressing
A subscriber can send a message to another subscriber on a remote location, which must be configured
on the local (sender’s) system. The sender addresses the message using the location ID of the remote
system plus the recipient’s extension number at the remote location.
When the message is sent to the remote subscriber, the sender will not hear a confirmation of the
recipient’s name or extension. This is blind addressing.
Spoken Name Confirmation for Remote Subscribers
Administrators can assign user IDs and extensions in the local Cisco Unity Express directory for
subscribers at existing remote locations. Additionally, administrators or other privileged subscribers can
record spoken names for these subscribers using the Administration via Telephone (AvT) feature.
If the local system has vCard information enabled, incoming vCard information updates the remote
subscriber information on the local system. The vCard information may contain the remote subscriber’s
first name, last name, and spoken name. This information is stored in the least recently used (LRU)
cache.
A sender on the local system can address a message to a remote subscriber using dial-by-name or
dial-by-extension. If a spoken name for the recipient is recorded, the sender hears the spoken name as
confirmation. If the recipient does not exist in the local directory but is in the LRU cache, the sender
hears the LRU cache information as confirmation. If the remote subscriber is not in the directory or the
cache, the sender receives the recipient’s location ID and extension.
Delivery Notifications
Cisco Unity Express supports the following message delivery notification types:
• Non-delivery receipt (NDR)
• Delayed delivery record (DDR)
Non-Delivery Receipt (NDR)
If the system cannot deliver a message to a remote site after 6 hours, the local sender receives a
non-delivery receipt (NDR) indicating the message was not sent or that the message was not delivered
to the recipient’s mailbox.
This receipt indicates the reason for nondelivery. If nondelivery is due to the recipient’s mailbox being
full, nonexistent, or disabled, the nondelivery message includes the sender’s original message. When the
sender plays the NDR, the sender can readdress and resend the original message or delete the message.
Each NDR counts against the sender’s mailbox capacity.
Delayed Delivery Record (DDR)
Cisco Unity Express sends a delayed delivery record (DDR) to the local sender’s mailbox after 60
minutes of trying to deliver the original message. Unlike the NDR, the DDR does not contain the original
message as an attachment and does not count against the sender’s mailbox capacity.
