Chapter 18 Configuring Advanced Voice Mail
Configuring Live Reply
VPIM (Network) Delivered Voice Mail
To support this feature, the network message delivered using VPIM between Cisco Unity Express nodes
or between Cisco Unity Express and Cisco Unity contains the E.164 number, starting in version 3.0 (if
it is configured and available for the subscriber).
You can configure the live-reply feature so that it can be used with existing VPIM capable systems that
send only the subscriber's mailbox number (which may or may not be the appropriate E.164 number)
instead of the E.164 number. Do this by setting up a rule to define each remote location in your
Cisco Unity Express configuration that will be used to determine which E.164 number to dial to reach
the author of the VPIM delivered voice mail. This determination is done based on network configuration
location settings.
You can configure this rule to use one of the following options as the sender’s E.164 number:
• Sender’s mailbox ID as the E.164 phone number. This number is found in the VPIM message header
from field in the digits before the “@” character.
• Combination of the configured network location prefix followed by the sender’s mailbox ID. The
network location prefix is given in the location subcommand with the command voicemail
phone-prefix prefix-digits.
• Combination of the network location ID followed by the sender's mailbox ID. The network location
ID is specified when defining a network location with the command network location ID
location-digits.
• Concatenation of network location ID, followed by network location prefix, followed by mailbox
ID.
• Concatenation of network location prefix, followed by network location ID, followed by mailbox
ID.
By default, Cisco Unity Express uses the E.164 number supplied by a peer 3.1 of later version system in
the VPIM header, if present. Otherwise it uses the configured rule to determine the E.164 number to use
for this message.
In some cases, you can reconfigure remote sites to use the mailbox ID as the E.164 number to dial for
live reply. You can use this configuration when:
• The Cisco Unity Express subscriber mailbox IDs are unique across the network and therefore, the
mailbox ID is the same as the subscriber extension.
• The Cisco Unified Communications Manager or Cisco Unified CME is also configured to dial from
site to site by subscriber extension.
You probably have overlapping extensions between sites. In this case, Cisco Unity Express could be
configured to use the remote systems phone prefix with the subscriber's mailbox ID to derive the E.164
number to dial. You can use this method if you configure your Cisco Unified Communications Manager
or Cisco Unified CME to implement this dial plan and transform the mailbox ID received in the VPIM
message into a unique E.164 address.
In addition to determining how to derive the E.164 phone number to use with live reply, you can also set
the precedence of the VPIM E.164 number over the rule derived phone number.
Limitations
Live-reply cannot apply call restrictions on a per-subscriber basis. Because the outbound dialing is from
Cisco Unity Express on behalf of the user, any restrictions on dialed numbers must be applied to all users
equally. There cannot be a privileged set of Cisco Unity Express subscribers that have a broader set of
