Introduction
These release notes describe new features, requirements, restrictions, and caveats for Cisco IP Communicator. These release notes are updated for every maintenance release and every major release but not for patches or hot fixes.

Before you install Cisco IP Communicator, we recommend that you review this document for issues that might affect your system.

System Requirements
•Network Requirements

•Server Requirements

•Client PC Requirements

Network Requirements
For Cisco IP Communicator to successfully operate as an endpoint, your network must meet these requirements:

•You must configure voice over IP (VoIP) on your Cisco routers and gateways.

•Make sure you configure all interfaces carrying media-type data (voice, video, web conferencing) between its two endpoints to non-autonegotiate speed and duplex (for example, set all ports to 100 MB full duplex). You must also configure Ethernet interfaces on routers and switches in the cloud in this way.

If the autonegotiate setting is retained, negotiation can occur at any time, and if it occurs during a UDP transmission, that data is lost. Because voice data is UDP, users can experience significant voice quality problems. Similarly if any logical data is transmitted over UDP, serious system impairment might occur.

•If Cisco IP Communicator is behind a firewall, you must open ports in the firewall. For details about the TCP and UDP port usage for Cisco Unified Communications Manager, see this URL:

http://www.cisco.com/en/US/products/sw/voicesw/ps556/prod_maintenance_guides_list.html

•Your IP network must support DHCP with Cisco Option 150 configured with your TFTP server addresses if you want Cisco Unified Communications Manager to auto-locate its TFTP server.

•To integrate with Cisco Unified Video Advantage, see the “Supported Cisco Unified Communications Manager Releases” section for the minimum Cisco Unified Communications Manager release.

•To integrate with Cisco Emergency Responder (CER), you need an available Ethernet port on a Cisco Ethernet switch. For details, see the Cisco Emergency Responder Administrator Guide.

——————————————————————————–

Note If the computer on which Cisco IP Communicator is running is plugged into the PC port on the back of a Cisco Unified IP Phone, Cisco IP Communicator is not discovered by the CER software. In this case, the Cisco Discovery Protocol (CDP) is blocked and is not detected by CER. Connecting Cisco IP Communicator directly to a switch port prevents this problem.

——————————————————————————–

Server Requirements
Cisco IP Communicator requires Cisco Unified Communications Manager or Cisco Unified Communications Manager Express for call processing. Before you deploy Cisco IP Communicator to users, make sure that Cisco Unified Communications Manager or Cisco Unified Communications Manager Express is set up properly to manage Cisco IP Communicator devices and to route and process calls. For more information, see the Cisco Unified Communications Manager Administration Guide or context-sensitive help in Cisco Unified Communications Manager Administration.

For an overview of configuration and deployment tasks involving Cisco Unified Communications Manager and Cisco Unified Communications Manager Express, see the Cisco IP Communicator administration guide at this URL:

http://www.cisco.com/en/US/products/sw/voicesw/ps5475/prod_maintenance_guides_list.html

——————————————————————————–

Note If Cisco IP Communicator does not appear in the Phone Type drop-down list in Cisco Unified Communications Manager Administration, install the latest support patch for your version of Cisco Unified Communications Manager: http://www.cisco.com/public/sw-center/sw-voice.shtml

Supported Cisco Unified Communications Manager Releases
These releases are supported with Cisco IP Communicator Release 2.1:

——————————————————————————–

Note Cisco Unified Communications Manager is formerly known as Cisco Unified CallManager.

——————————————————————————–

•Cisco Unified Communications Manager Release 6.1 (SCCP and SIP)

•Cisco Unified Communications Manager Release 6.0 (SCCP and SIP)

•Cisco Unified Communications Manager Release 5.1 (SCCP and SIP)

•Cisco Unified Communications Manager Release 5.0(4) (SCCP and SIP)

•Cisco Unified Communications Manager Release 4.2(3) SR1 (SCCP)

This Cisco Unified Communications Manager release is now the minimum release with or without Cisco Unified Video Advantage integration. For details about client PC requirements when running Cisco IP Communicator with Cisco Unified Video Advantage, see Table 2.

Interoperability Notes for Cisco Unified Communications Manager
These interoperability notes apply:

•While Cisco IP Communicator registers and runs many of the functions within Cisco Unified Communications Manager Release 6.1, 6.0 or 5.1, it does not support some of the new features introduced in these releases because Cisco IP Communicator is based on the Cisco Unified Communications Manager Release 5.0 7970 phone firmware. Similarly, some features might not be available when registering Cisco IP Communicator with Cisco Unified Communications Manager Express.

•Cisco IP Communicator is not supported with Cisco Unified Communications Manager Assistant Release 6.0 or 5.1 (formerly known as Cisco Unified CallManager Assistant and Cisco IP Manager Assistant [IPMA]).

•When Cisco IP Communicator is using SIP as its call-control protocol, it does not interoperate with:

–WebDialer

–Cisco Unified Video Advantage

–Cisco Unified Communications Manager Assistant

•To add support for security features in Cisco IP Communicator, download and install the Cisco Unified Communications Manager Release 4.x device pack from this URL:

http://www.cisco.com/pcgi-bin/tablebuild.pl/callmgr-42

These versions are supported:

–Release 4.2: devpack 05

–Release 4.1: devpack 31

These releases are supported with Cisco IP Communicator Release 2.1:

•Cisco Unified Communications Manager Express Release 4.1 (SCCP)

•Cisco Unified Communications Manager Express Release 4.0 (SCCP)

•Cisco Unified Communications Manager Express Release 3.3 (SCCP)

——————————————————————————–

Note When Cisco IP Communicator is running SIP as its call-control protocol, it does not support SRST or Cisco Unified Communications Manager Express. (CSCsh69835)
