Directory Update Processing That Occurs on the Cisco Unity VPIM Bridgehead Server

The CsVPIMConnector service running on the VPIM bridgehead server monitors the

UVPIM_<Servername> mailbox for directory messages. When the CsVPIMConnector service receives a directory message indicating that a new VPIM subscriber should be created, it also checks additional Subscriber Creation settings on the delivery location to determine:

Which template to use when creating VPIM subscribers

How to map the parsed text name of the VPIM subscriber to a first name, last name, and display name

How to map the phone number to an extension

Whether or not VPIM subscribers with no recorded voice names are allowed

The service uses SQL Server to create or update the VPIM subscriber on the VPIM bridgehead server. From the SQL Server database, the subscriber information is replicated to Active Directory, where a mail-enabled contact is created.

When the CsVPIMConnector service receives a directory message indicating that an existing VPIM subscriber should be modified, it checks to see whether the delivery location is configured to have the subscriber information updated with every incoming VPIM message, or only on messages where the text name has changed. The service takes the text name from the incoming message and applies the rules that have been configured to map the text name to a display name. If the option is selected that allows updates only when the text name has changed, the service compares this new display name to the display name on the VPIM subscriber record to determine whether the subscriber record should be modified. If the modification is allowed, the CsVPIMConnector service also checks to determine whether the delivery location is configured to allow display name updates. If so, the service will modify the first and last name fields and the recorded voice name, but will leave the display name unchanged. Otherwise, all of these fields will be updated.

For example, you can configure a location as follows:

Display names will be created as “Firstname Lastname - Seattle”

Updates are allowed only when the text name changes

Display name updates are allowed

In this circumstance, if a VPIM subscriber exists with the display name “Jessie Smith - Seattle” and an incoming message is received from Jessie Smith, no action will be taken. If the display name for Jessie Smith on the remote system is changed to “Jess Smith,” a modification will be triggered the next time Cisco Unity receives an incoming message, and the first name and display name will be updated accordingly.

In other cases, a last name may change or a given mailbox number may be reassigned to a new person, so it is not recommended that modifications be allowed while display names updates are disallowed, as this could result in a first and last name contradicting the display name. The rule for mapping display names can be configured so that most desired display name conventions can be maintained when VPIM subscribers are automatically created or modified.

When the CsVPIMConnector service receives a directory message indicating that an existing VPIM subscriber should be deleted, it checks the reason code included in the message. If the reason code indicates that the mailbox does not exist (SMTP error code 5.1.1), the CsVPIMConnector service will delete the VPIM subscriber record. All associated objects and properties, including public and private distribution list membership, will be deleted from the SQL Server database on the VPIM bridgehead server. From the SQL Server database, the change will be replicated so that the Active Directory contact is removed.
