Determining How to Overwrite a Caller ID with a FindMe ID
Cisco VCS can only overwrite the Caller ID with a FindMe ID if:
■
the call signaling passes through the Cisco VCS (or Cisco VCS cluster) that hosts the FindMe account
■
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:
provided in the call matches one of the following:
—
a FindMe device which is only found in a single FindMe account
—
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.
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.

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.)

FindMe Accounts Hosted on Hifferent Cisco VCSs in a Network
FindMe accounts can be distributed across multiple Cisco VCSs (or Cisco VCS clusters), but each individual account
can be hosted on only one Cisco VCS (or Cisco VCS cluster).

Therefore, care must be taken in designing system topologies to ensure that caller ID can always be overwritten.
For example, if two users have their accounts on a VCS Control, but both are working from home on endpoints that are
registered to a VCS Expressway (which has a traversal zone to the VCS Control):

If one user calls the other user's FindMe ID, their caller ID will be overwritten by their FindMe ID, as the call
signaling will go via the VCS Control (where the user account is hosted).

If one caller calls the other user's endpoint URI directly, the call signaling will go through the VCS Expressway, but
not the VCS Control. In this scenario the caller ID will not be overwritten with the FindMe ID as the signaling would
not pass through the VCS Control. (It is recommended that users call FindMe IDs rather than individual device
URIs.)

FindMe and Presence
The Cisco VCS aggregates presence for each of the devices associated with a user's current active FindMe location.
However, it can only do this for devices whose presence is managed by a Presence Server that resides on the same
Cisco VCS (or Cisco VCS cluster) that hosts the relevant FindMe account.
