Enhance Communications and Simplify Management
Cisco Unified CallManager software is the call-processing component of the Cisco Unified Communications system. It is a scalable, distributable, and highly available enterprise IP telephony call-processing solution.
Cisco Unified CallManager Version 5.0 enhances application delivery through the support of line-side Session Initiation Protocol (SIP) and SIP trunk-side enhancements. These enhancements facilitate increased interoperability with third-party applications and devices, and provide the foundation for supporting innovative new presence-based applications. In addition, Cisco Unified CallManager 5.0 simplifies deployment and management by supporting a Linux-based appliance model implementation. This version also features networking and administration enhancements, including support for Cisco RSVP Agent which enables more efficient use of networks.
Cisco Unified CallManager 5.0 includes the following features:
Line-side SIP support for SIP devices and applications
SIP trunk-side enhancements
Support for presence-based applications including Cisco Unified Personal Communicator and Cisco IP Phone Messenger
Appliance model implementation
Administration enhancements
Networking enhancements including Cisco RSVP Agent support for more efficient use of networks

CISCO UNIFIED CALLMANAGER VERSION 5.0 ENHANCEMENTS
SIP Trunk and Endpoint Support
SIP trunk and endpoint support provides enhancements to support SIP and host SIP phones, improving interoperability and opening ways to develop innovative applications. Cisco Unified CallManager supports coexistence of SCCP and SIP phones, allowing migration to SIP while protecting investments in existing devices. Cisco Unified CallManager 5.0 includes the following major SIP functions:
• Native support of SIP devices
• CTI for ISP phones
• Presence information for SIP devices
• FCAPS enhancements to support SIP
• SIP trunk enhancements for external applications, such as conferencing and presence
• Third-party SIP devices supporting RFC 3261
• SIP line-side RFCs: RFC 3261, 3262, 3264, 3265, 3311, 3515, 3842
• SIP trunk RFC support: RFC 2833, 2976, 3261, 3262, 3264, 3265, 3311, 3515, 3842, 3856, 3891
Licensing
Application and phone software licenses are enforced. The system manages the maximum number of devices that can be provisioned.
• Each device (Cisco Unified IP phones, third-party devices and video devices) provisioned in the system corresponds to a number of Device License Units (DLUs) depending on its capabilities; the total number of units is managed in Cisco Unified CallManager to determine capacity.
• DLUs must be purchased to cover the number of devices connected to Cisco Unified CallManager.
• Third-party SIP devices require DLUs for operation with Cisco Unified CallManager.
