Licensing Model
© 2008 Cisco Systems, Inc. All rights reserved.
CIPT1 v6.0—1-22
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).
© 2008 Cisco Systems, Inc. All rights reserved.
CIPT1 v6.0—1-23
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
© 2008 Cisco Systems, Inc. All rights reserved.
CIPT1 v6.0—1-24
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 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.
