Cisco Unified CommunicationsOperating System


Cisco Unified Communications Operating System

Appliance operating system (based on Red Hat Linux)

Operating system updates provided by Cisco(along with application updates)

Unnecessary accounts and services disabled

IDS as the database

DHCP server

Cisco Security Agent

Cisco Unified Communications operating system is also used for these other Cisco Unified Communications applications:

– Cisco Emergency Responder 2.0

– Cisco Unity Connection 2.0

– Cisco Unified Presence 6.0


Cisco Unified Communications Operating System Access

Root and other common default accounts of native operating system disabled.

No native operating system access.

– Only Cisco CLI and GUI can be used.

– Cisco CLI can be used to troubleshoot GUI access. No access to native operating system debug interfaces.

– Traces, alarms, and counters can be enabled and monitored through Cisco CLI and GUI.

No direct access to file system.

– Only some files and directories accessible through Cisco CLI and GUI. Customer can activate remote account support for specific time for Cisco

TAC access.


Cisco Unified Communications Manager Database


Cisco Unified Communications Database

IBM IDS database stores

– Static configuration data: Servers and enabled services within the cluster Devices (phones, gateways, and trunks) Users, dial plan, etc.

– Dynamic data utilized by user-facing features: Call Forward All, MWI Privacy, DND Hunt group login status, etc.

Basically a single master database model

– R/W database access only for publisher (read-only for subscribers)

– Exception: Subscribers do allow R/W access for user-facing features


Services That Rely On The Publisher

Component Function When

CCMAdmin Provisions everything Always

CCMUser Provisions user settings Always

BAT Provisions everything Always

TAPS Updates device records Always

AXL Provisions everything Always

AXIS-SOAP Enables and disables services Sometimes

CCM Inserts phones Autoregistration only

LDAP Sync Updates End-user table Always (local)

License Audit Updates License tables Always (local)

These services are not available in the event of a publisher failure.


User-Facing Features

Call Forward All (CFA)

Message Waiting Indication (MWI)

Privacy Enable/Disable

Do Not Disturb Enable/Disable (DND)

Extension Mobility Login (EM)

Hunt Group Logout

Device Mobility

CTI CAPF status for end users and application users

Credential hacking and authentication

These features do not rely on the availability of the publisher because necessary data can be written to subscribers.


Cisco Unified Communications Manager Release 6.0 Database Replication

Replication is fully meshed.

Most data are still hub-and-spoke (replicated from publisher to subscribers).

Only user-facing features data are writable on a subscriber and bidirectionally replicated between all servers.

Database Access Control

DB access between members of a cluster is protected

– By IP access control (dynamic firewall "iptables")

– By security password Special configuration procedure required to enable database access for subscribers

– At publisher, using Cisco Unified Communications Manager Administration, add subscriber to list of servers before installation of subscriber

– During subscriber installation, enter same DB security password that was configured during installation of publisher

Cisco Unified Communications Manager Licensing Model


Cisco Unified Communications Manager Licensing

There are three types of licenses.– Software license is required for using CUCM 6 software.– Device license units required for devices (phones). – Node licenses required for each call-processing Cisco Unified

Communications Manager server within the cluster. Licenses are required per cluster and provided by license files. License file is bound to MAC address of publisher (running the

licensing service). Cisco Unified CM cluster continues to work if licensing service is

stopped (but no configuration changes allowed).


Device License Units Amount of device license units

depends on device type and device capabilities.

– Cisco phone or third-party phone

– Number of lines

– Video capabilities

– Etc.

Number of units required per device can be viewed from Cisco Unified Communications Manager Administration.

Device License Units


License File Specifics

The license file contains the following information:

– MAC address of the license server (publisher)

– Version (major release) of the Cisco Unified Communications Manager software

– Number of node licenses

– Number of device license units License files are additive (multiple license files can be loaded). Cisco FlexLM process is used to obtain licenses. License file integrity is assured by a digital signature. Upgrade considerations

– From Cisco Unified CallManager Release 4.x An interim license file is created during upgrade. No changes possible until replaced by real license file.

– From Unified Cisco Unified CallManager Release 5.x A software license has to be added (Cisco Unified CM 5.x only required node licenses and

device license units).

Obtaining Additional Licenses

Obtaining additional device units and nodes licenses uses the same process as obtaining a new license file. The customer places an order for the additional licenses for a license

server (MAC address of publisher).

When the order is received, Cisco.com generates a license file with the additional count.

This new license file will have to be uploaded to the license server and will be cumulative.

Summary

Cisco Unified Communications is a comprehensive communications system of voice, video, data, and mobility products and applications over a single network infrastructure using standards-based Internet Protocol.

Cisco Unified Communications Manager functions include call processing, signaling and device control, dial plan administration, phone feature administration, directory services, and a programming interface.

Cisco Unified Communications Manager must be installed on a supported Cisco MCS platform or third-party server hardware approved by Cisco.


Summary (Cont.)

Access to the system is only allowed through the use of Cisco CLI and GUI tools.

Cisco Unified Communications Manager uses an Informix Dynamic Server (IDS) database, and configuration information in the database is replicated from the first node to all subsequent nodes within a cluster.

Three type of licenses are required: devices, applications, and software.

License files are uploaded using Cisco Unified Communications Manager Administration GUI.
