In addition to manually creating, modifying, and deleting VPIM contacts, you can configure Unity Connection to automatically
update records in the VPIM contact directory based on information that is contained in incoming VPIM messages. The settings
that control whether the creation, modification, and deletion actions occur automatically, and how the incoming information
is used to create or modify a record, can be individually configured for each VPIM location. By default, no automatic directory
updates occur for any VPIM locations.
Depending on the Contact Creation settings that you select for each VPIM location, Unity Connection uses information from
the header of an incoming VPIM message. If a VPIM message is received from a sender on a VPIM location that is configured
to allow automatic VPIM contact creation, and no existing VPIM contact matches the information of the sender, a new VPIM contact
record is created, provided that the VPIM message contains:
Additional Contact Creation settings allow you to specify how to map the parsed text name of the VPIM contact to a first name,
last name, and display name, and how to map the phone number to an extension.
Changes to the Map VPIM Contact Extensions setting on the Contact Creation page for a VPIM location affect only VPIM contacts
that are created after the setting is saved. VPIM contacts that already existed before the Map VPIM Contact Extensions setting
is changed are not automatically updated. You must manually change the extension for each previously existing VPIM contact
for that VPIM location.
If a VPIM message is received from a sender on a VPIM location that is configured to allow automatic VPIM contact modification,
and an existing VPIM contact matches the sender information, the VPIM contact can be updated. You can select whether VPIM
contact information is updated each time a message is received from a VPIM contact, or only when a message is received from
a VPIM contact whose text name has changed since the directory entry was created. You can also decide whether or not to allow
an update to the display name when a modification is made.
If a message from a Unity Connection user to a VPIM contact results in a non-delivery receipt (NDR), indicating that the message
was undeliverable because the intended recipient does not exist (SMTP 5.1.1), and if the VPIM location is configured to allow
automatic VPIM contact deletion, the VPIM contact is deleted.
You can update the VPIM location contact creation settings using Cisco Unity Connection Administration.
