Definition 1 of 24
CUE includes basic IVR capabilities that allow callers to move through a menu system,
providing more features than the auto-attendant. For example, a user can query a corporate
database for a bank account balance or the date of a last payment received.

CUCM Database Relationship
Definition 2 of 24
Holds & maintains the master copy of the CUCM IBM Informix database. Sends a copy via TFTP
to all subscribers. Supports up to 8 subscribers
In smaller environments (500 IP phones or less), it's perfectly fine to use the Publisher for call
processing and database management. However, once you exceed that number, it's generally
a best practice to pull the Publisher out of call processing and leave that work to the
Subscribers. Likewise, once you exceed 1,250 users, Cisco recommends moving the TFTP
server role to a dedicated server.

Full support for audio and video telephony:
Appliance-based operation: Modern CUCM versions run as an appliance, which means the
underlying operating system is hardened (secured) and inaccessible.
Redundant server cluster: Scales to 30,000 IP phones in insecure mode or 27,000 in secure
mode.
Intercluster and voice gateway control and communication:
Built-in Disaster Recovery System (DRS): As a built-in feature, the CUCM DRS service allows
you to back up the CUCM database (and any additional files you'd prefer) to a network device
or over Secure FTP (SFTP).
VMWare Virtualization Support: If you love VMWare, you'll love the fact that CUCM 8.0 is
supported in a VMWare ESXi environment.
Directory service support or integration: VoIP networks can use network user accounts for a
variety of purposes (phone control, attendant console control, and so on). CUCM has the
capability to be its own directory server to hold user accounts or it can integrate into an
existing corporate directory structure

Definition 7 of 24
Just like the name sounds, the runtime data encompasses anything that happens in "real time" in
the CUCM cluster. For example, when a device registers with a CUCM server, it communicates
to all the other servers that it now "owns" that IP phone. CUCM uses a method designed
specifically by Cisco for this type of communication: Intracluster Communication Signaling
(ICCS).
