Cisco Unified Communications Manager

(CUCM)

Hi-Level Overview


CUCM :: Capabilities •  Fully-featured Voice and Video Solution •  Ability to cluster most services to provide five 9’s resiliency •  Typically for larger deployments (up to 30,000 phones per

cluster) •  Runs on a hardened RHEL platform as an appliance (no

direct shell access) –  Individual 1U rackmount Cisco UCS servers –  Cisco UCS blade servers running in VMWare ESXi

•  Stores all data in an IBM Informix DB


CUCM :: High-Level Features •  Call Processing Engine (CPE) •  Configuration done via Web UI •  Music on Hold server •  Conferencing server •  Directory (integrated or LDAP sync) and Presence Services •  Has integrated Disaster Recovery System (DRS) for Backup

& Restore •  Cisco Unified Serviceability and Cisco RTMT provide ability

for management and troubleshooting


CUCM :: Per-Server Specs •  Cisco UCS Servers:

–  Cisco UCS C210 Rack-Mount Server :: 7,500 (endpoints/server) –  Cisco UCS B200 Blade Server :: 7,500 –  Cisco UCS C200 Rack-Mount Server :: 1,000

•  Cisco MCS Servers: –  Cisco MCS 7845-I3 :: 10,000 –  Cisco MCS 7845 :: 7,500 –  Cisco MCS 7835 :: 2,500 –  Cisco MCS 7825 :: 1,000 –  Cisco MCS 7816 :: 500 –  Cisco MCS 7815 :: 300

•  On any server, requires min of: –  2GHz CPU –  2GB RAM –  72GB HDD


CUCM :: UCS Server Specifics •  CUCM 8 is first version supported in VMWare •  UCS Hardware must be used (blade or rackmount) •  VMWare ESXi 4.0 with SAN (must use .ova file to install) •  Migration can be preformed using DRF •  Mixed hardware cluster (Phys and Virtual) •  License key for CUCM uses VMWare virtual MAC address


CUCM :: VMWare Specifics •  2 virtual CPUs •  6-GB RAM •  Two 80-GB hard disks at SCSI id 0:0 and 0:1 •  Only a UCS Version 7 VM is supported •  Supports up to 7500 users per VM •  No USB support (Secure keys, MoH live feeds, etc) •  Backups for the Virtual Machine (VM) must be via SFTP


CUCM :: Server Roles •  CUCM DB Publisher server (Pub) •  CUCM DB Subscriber server (Sub)

–  Typically run publisher server strictly for DB changes/sync, MVA, Presence, Dir Sync with LDAP – however it can be used as a CPE

–  Can have up to 8 subscriber servers running as CPE’s –  Can have up to 3 CPE’s per Unified CM Group –  Can have up to 2 subscriber servers running as TFTP servers –  Additional subscriber servers can be used as Media servers

•  e.g. MoH, Annunciator, Conference, MTP


CUCM :: DB Roles •  IBM Informix DB – Structured Query Language (SQL)

–  “Owned” and Managed by the Publisher server –  One-way replication (e.g. from Pub to Subs) –  Most configuration is made on the Pub DB server –  However there are some DB fields changed on Sub servers local to where phones are

registered, called User Facing Features (UFF), then replicated up to Publisher (if alive) •  Call Forward All (CFA) •  Message waiting indicator (MWI) •  Privacy Enable/Disable •  Extension Mobility login/logout •  Hunt Group login/logout •  Device Mobility •  Certificate Authority Proxy Function (CAPF) status for end users and applications users •  Credential authentication


CUCM :: Cluster Communication •  Intra-Cluster Communication Signaling (ICCS)

–  TCP ports 8002 - 8004 –  Replicates all run time data between all servers in cluster that are

CPE’s (i.e. that are running the “Cisco CallManager” service)

•  Call Detail Records (CDR) and Call Management Records (CMR) –  Logged by CPE taking the call (where phone or gateway is registered) –  Data periodically pushed up to Publisher server –  Cisco CDR Analysis and Reporting (CAR) or any 3rd party billing

application servers always point to and collect data from Publisher

CUCME :: High-Level Features •  Call Processing Engine (CPE) •  Device Control via VoIP (SIP or SCCP) Signaling •  Configuration via Command Line (IOS CLI) or Web UI •  Directory •  Music on Hold server •  Conferencing server •  Custom applications using TCL scripting language such as

Basic ACD (B-ACD)
