4 Cisco Unified Communications Manager (CUCM) Hi-Level Overview

5 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

6 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

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

8 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

9 2 virtual CPUs 6-GB RAM CUCM :: VMWare Specifics 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

10 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

11 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

12 CUCM :: Cluster Communication Intra-Cluster Communication Signaling (ICCS) TCP ports 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 3 rd party billing application servers always point to and collect data from Publisher

13 CUCM :: Traffic Flow PSTN CUCM Cluster TDM Signaling/Media SIP / SCCP Signaling RTP Media (Voice/Video)

14 Cisco Unified Communications Manager Express (CUCME) Hi-Level Overview

15 CUCME :: Capabilities Fully-featured Voice and Video Solution running in Cisco Router IOS Typically for smaller deployments (up to 350 phones) Also can be used as to provide high availability fallback services for large and small branch offices normally using CUCM (a.k.a. SRST) 3rd Party Computer Telephony Integration(CTI) Single-Site or Multi-Site Deployments Directory and Presence Services Interworking with CUCM Support for Remote Phones

16 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)

17 CUCME :: Traffic Flow CUCME SIP / SCCP Signaling RTP Media (Voice/Video)

18 CUCME :: Specs Routers that Support CME, Sizing ISR-G :: 35 Phones :: 0 SM* Slots :: 8 T1/E1 s ISR-G :: 50 Phones :: 1 SM Slots :: 12 T1/E1 s ISR-G :: 100 Phones :: 1 SM Slots :: 12 T1/E1 s ISR-G :: 150 Phones :: 2 SM Slots :: 16 T1/E1 s ISR-G :: 250 Phones :: 2 SM Slots :: 16 T1/E1 s ISR-G :: 350 Phones :: 4 SM Slots :: 24 T1/E1 s *SM = Service Module

19 CUCME :: Specs, cont d Routers that Support CME, Sizing ISR :: 15 Phones :: 0 Network Module (NM) Slots ISR :: 25 Phones :: 0 NM Slots ISR :: 35 Phones :: 1 NM Slots ISR :: 50 Phones :: 1 NM Slots ISR :: 100 Phones :: 2 NM Slots ISR :: 175 Phones :: 2 NM Slots ISR :: 250 Phones :: 4 NM Slots RISR :: 20 Phones :: 0 NM Slots RISR :: 48 Phones :: 0 NM Slots

20 Cisco Unity Connection (CUCx) Hi-Level Overview

21 CUCx :: Capabilities Integrated Messaging Server (Voic w/ retrieval) Typically for larger deployments (up to 20,000 VM boxes per server Ability to cluster/failover services (Active/Active failover) Fully featured Auto Attendant or Voice Menu server Directory Services w/ TTS w/ Ability to sync from LDAP Supports MS Exchange integration for Calendaring and IMAP integration for Integrated/Unified Messaging Survivable Remote Site Voic (SRSV) support Digital Networking with other CUCx servers for large deployments Voice Profile Internet Mail (VPIM) for networking to other VM servers Messages are stored in local FS (vs Unity stored in MS Exchange)
