b. End User accounts and passwords are replicated to CUCM.
c. LDAP check the user accounts in CUCM and replicates only those that also exist in LDAP.
d. End User accounts that exist in LDAP are replicated to CUCM, unless the LDAP sn attribute is blank.
Whick is true of LDAP Synchronization Agreements?

d. All Sync Agreements must run on a regular scheduled basis.
e. Only one Synch agreement can be made with a single LDAP system.
Detail the IP Phone registration process.
- 1. Phone obtains power, (POE or brick)
- 2. phone loads locally stored firmware image
- 3. phone learns of Voice VLAN ID via CDP from the switch
- 4. Whone uses DHCP to get an IP address, SNM, Default GW and Option 150 (TFTP server IP address)
- 5. Phone gets config file SEP<mac_add>.cnf.xml file from TFTP server.
- 6. Phone registers with primary CUCM server listed in its config file. CUCM sends softkey template to the phone using SCCP messages.
What is different about phone registration between SCCP and SIP signaling?
During registration, SEP file contains CUCM server, TCP Ports for SCCP signaling and firmware version. SCCP signaling then sends DNs, softkeys and speed dial info.
SIP sends all that info in the SEP file. SIP has no extra signaling to send the DNs and Speed dials so the SIP files are larger than SCCP.
What are the required Configuration elements in CUCM for IP Phones?
Book lists 12.
- Device pool - common attributes, (call center)

- Location - controls bandwidth
- Date/Time - time zone
- Phone NTP Reference -
- Device Defaults

- Phone Button Template

Why use LDAP sync or authorization?
It makes administration easier, Users, passwords, etc don't have to be maintained in two seperate databases.
What is LDAP sync?
Some but not all user data is maintained in LDAP and replicated to CUCM. LDAP user attributes become read only in CUCM.
CUCM used DirSync to perform LDAP sync.
*** with LDAP sync, user passwords are still maintained in the CUCM database. This can cause confusion.
What is LDAP authorization?
This redirects password authentication to LDAP providing single sign-on.
What is the one user attribute that must be mapped to a LDAP field for integration to occur.
CUCM UserID mapped to LDAP:
- (one of the following)
- Telephone Number
How many admin web interfaces (pages) does CUCM provide?
CLI is not a web interface
What 2 accounts are created an install?
- platform admin (CMPlatformAdmin) – DRS and OS and CLI pages
- application admin (CMMasterAdmin) - CUCM admin, Unified Serviceability, Unified reporting ,
Define roles and groups relationship for administration.
- Users are asigned to a Group, Groups are assigned a role.
- Roles drive what privledges are assigned to the user (thru the group).
What are the 3 privledges?
- No Access
- Update (think execute)
How many roles are defined by default in CUCM 8.0?
How many default Groups are there?
