Determining the FindMe ID for a caller
VCS can only overwrite the Caller ID with a FindMe ID if:
n
the call signaling passes through the VCS (or VCS cluster) where the FindMe data is held
n
the VCS can identify a FindMe as the owner of the endpoint caller ID
If either of these conditions are not met, the incoming caller ID will be passed through unchanged.
The VCS identifies a FindMe as the owner of the endpoint caller ID if the incoming caller ID provided in the
call:
call:
n
matches a FindMe device which is only found in a single FindMe account
or
n
matches a single principal FindMe device (if the same device address is associated with more than one
FindMe profile)
FindMe profile)
Principal devices
Note that principal devices are designed to be key devices for the user who owns them:
n
A device is identified as a principal device if it has been configured by the VCS administrator in the
Principal devices
section of the user account page (
Users > FindMe accounts
), then select or create an
account).
n
Users cannot delete principal devices from the list of FindMe devices in an account.
Known limitations

Any change to a user account Display name is immediately reflected in phone books and the display name
returned in FindMe searches.

However, the caller ID display name in SIP messaging is only updated after the relevant Jabber Video is re-
provisioned (for example, after signing out and signing back in again).
