System 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.
  • 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 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 will not be discovered by the CER software. In this case, the Cisco Discovery Protocol (CDP) will be blocked and will not be 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:

Connectivity 384 kbps network connection

Note


Using video with Cisco IP Communicator over a corporate wireless LAN can result in poor audio and video quality. Video calls can be placed or received on a remote wireless LAN connection with a minimum broadband link of 384kbps/384kbps. For best results, we recommend that you use video over a wired Ethernet connection whenever possible.


Supported Audio Devices

While Cisco does perform basic testing of selected third-party headsets and handsets for use with Cisco IP Communicator, it is ultimately the customer's responsibility to test this equipment in their own environment to determine suitable performance. Due to the many inherent environmental and hardware differences in locations where Cisco IP Communicator is deployed, there is not a single best solution that is optimal for all environments.

Cisco provides integration with the following Jabra headsets as a convenience for our customers:

  • G.711a
  • G.711u
  • G.722
  • G.729a
  • G.729ab (SCCP only)

Note


The Cisco linear wideband audio codec (uncompressed wideband, 16 bits, 16 k hz) is not supported.



Note


When the option "Optimized for Low Bandwidth" is enabled, the following audio codecs are used: iLBC, G.729a, and G.729ab.


Supported VPN Software Client Notes

  • If running Cisco VPN Client software, version 5.0 or later is required.
  • If running Cisco AnyConnect software, version 3.0 or later is required.
  • The VPN client must assign an IP Address when connecting using VPN. Cisco IP Communicator only works with the VPN Software that creates a virtual interface and has an IP Address allocated to it. (CSCso09529)

Unsupported Appliances

Cisco IP Communicator is not supported with Cisco® ASA 5500 Series Adaptive Security Appliances with Phone Proxy for Remote Access.

Voice Quality

Cisco IP Communicator is designed to provide premium voice quality under a variety of conditions; however, in some instances users may notice interruptions of audio transmission or temporary audio distortions ("Artifacts") which are considered a normal part of the applications operation.

These artifacts should be infrequent and temporary when using:

  • Cisco IP Communicator on a workstation meeting the recommended configuration requirements.
  • A network that meets the recommended quality criteria in the Cisco Unified Communication Solution Reference Design Document.

We take reasonable measures to interface with the operating system in ways that decrease the likelihood that other applications running on the system will interfere with softphone audio and video quality. However, the shared nature of system environments in which these products run is very different than a closed environment like Cisco IP Phones and we cannot guarantee equivalent performance.

The following are some conditions that may cause artifacts:

  • Spike in usage of the personal computer's CPU - where CPU utilization is between 75 and 100% - due to launching applications, system processes or processing happening within other applications running.
  • The system is running low on available physical memory.
  • Other applications using large amounts of bandwidth to or from the workstation to the network.
  • Other network bandwidth impairments.
  • Dynamic reduction in CPU clock speed due to power management policy (for example, laptops running on battery power) or thermal protection causing the CPU to run in a more highly loaded condition.
  • Any other condition that causes the application to lose timely access to the network or audio system, for example, interference from third-party software.

Avoiding or recovering from the conditions previously listed will help minimize audio distortion artifacts.

New and Changed Information

Installation Notes

  • AutoUpdate: As of release version 2.x, Cisco IP Communicator does not support AutoUpdate functionality provided in any release of Cisco Unified Communications Manager. You must use a software deployment tool and the Cisco IP Communicator installer to update the application. If you previously specified a default or nondefault software load in Cisco Unified Communications Manager on the Device Defaults Configuration window, you must remove it.
  • Windows Vista Sound Control Panel issues:
    • If you rename an audio device through the Sound Control Panel after tuning it, it might need to be retuned the next time you use Cisco IP Communicator. (CSCsi24821)
  • With a Windows Vista installation you must disable the UAC setting in the user account for Cisco IP Communicator to send DSCP marking information (CSCta28077) or use a Windows policy-based QoS (CSCti25333).
  • Cisco IP Communicator freezes intermittently when the Windows Search Service is running. (CSCtd04400)
  • In order for Cisco IP Communicator to operate with an ASA proxy, Cisco IP Communicator must provision an LSC certificate from a Cisco Unified Communications Manager in mixed mode.
