Device Profiles and Templates Overview
This chapter explains how to configure device profiles and templates. For information about configuring specific features, see the Feature Configuration Guide for Cisco Unified Communications Manager at http://www.cisco.com/c/en/us/support/unified-communications/unified-communications-manager-callmanager/products-maintenance-guides-list.html.
A device profile defines the services, features, and directory numbers that associate with a particular device. You can configure a device profile and then you can assign the user device profile to a user, so that when the user logs in to a device, those features and services are available on that device.
SIP Profiles for End Points
A SIP profile comprises the set of SIP attributes that are associated with SIP endpoints. SIP profiles include information such as name, description, timing, retry, call pickup URI, and so on. The profiles contain some standard entries that cannot be deleted or changed.
Device Profiles and Templates
Cisco Unified Communications Manager also supports a default device profile. Cisco Unified Communications Manager uses the default device profile whenever a user logs on to a phone model for which no user device profile exists.
Peer-to-Peer Image Distribution
Limits congestion on TFTP transfers to centralized TFTP servers.
Eliminates the need to manually control firmware upgrades.
Reduces phone downtime during upgrades when large numbers of devices are reset simultaneously.
In most conditions, the peer firmware sharing feature optimizes firmware upgrades in branch deployment scenarios over bandwidth-limited WAN links.
When the feature is enabled, it allows the phone to discover similar phones on the subnet that are requesting the files that make up the firmware image and to automatically assemble transfer hierarchies on a per-file basis. The individual files that make up the firmware image get retrieved from the TFTP server by only the root phone in the hierarchy and are then rapidly transferred down the transfer hierarchy to the other phones on the subnet using TCP connections.
