Determining how to overwrite a caller ID with a FindMe ID
Cisco VCS can only overwrite the Caller ID with a FindMe ID if:
n
the call signaling passes through the Cisco VCS (or Cisco VCS cluster) that hosts the FindMe account
n
the Cisco VCS can identify a FindMe as the owner of the endpoint caller ID; it can do this if the incoming
caller ID provided in the call matches one of the following:
caller ID provided in the call matches one of the following:
l
a FindMe device which is only found in a single FindMe account
l
a single principal FindMe device (if the same device address is associated with more than one FindMe
location).
location).
If either condition is not met, the Incoming caller ID is passed through unchanged.
Principal devices
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 is the initially configured device when the FindMe account
was created.

n
Users cannot delete a principal device from their account. Administrators can modify whether a device is a
principal device or not on the
principal device or not on the

FindMe in a Cisco VCS cluster
When FindMe is used with a Cisco VCS cluster, the FindMe option key must be enabled on every Cisco
VCS peer in the cluster. The FindMe database is replicated across all peers in the cluster so that FindMe
functionality can be performed on any peer that a call traverses.

clusters.
Microsoft Lync and the Cisco VCS B2BUA
When FindMe is used with a cluster of “Lync gateway” Cisco VCSs, each peer in the cluster registers a
portion of the FindMe users to Microsoft Lync so that call loading is shared across cluster peers. (Calls from
Lync to Cisco VCS are delivered by Lync to the Cisco VCS that registered the user.)
