Cisco IP Communicator

Cisco IP Communicator is a Microsoft Windows-based application that delivers enhanced telephony support through personal computers. It is easy to deploy and features some of the latest technology and advancements available with IP communications today. This application endows computers with the functions of IP phones, providing high-quality voice calls on the road, in the office, or from wherever you can access the corporate network. Cisco IP Communicator supports Session Initiation Protocol (SIP) as well as the Cisco Unified Communications Manager Skinny Client Control Protocol (SCCP).

Cisco IP Communicator is designed for users who require a supplemental telephone when away from their desk or traveling or telecommuting. When using Cisco IP Communicator remotely, you are not just taking your office phone extension with you - you still have access to the same familiar phone and video telephony services you have in the office. This advantage boosts business collaboration and responsiveness, and helps organizations keep pace with today’s mobile business environment.

Cisco IP Communicator works with Cisco Unified Video Advantage to bring video telephony to the communications experience. Now, telecommuters and mobile employees using Cisco IP Communicator can enhance their communications with video. When calls are made through Cisco IP Communicator, available video is automatically displayed through Cisco Unified Video Advantage. It is as easy as making a telephone call.

Cisco IP Communicator uses the Cisco Unified Communications Manager call-processing system to provide advanced telephony features and voice-over-IP (VoIP) capabilities. Access to eight telephone lines (or a combination of lines and direct access to telephony features) is included. When registered to the Cisco Unified Communications Manager system, Cisco IP Communicator has the capabilities of a full-featured Cisco Unified IP phone, including the ability to transfer calls, forward calls, and add participants to an existing conference call. As a result, system administrators can provision Cisco IP Communicator as they would any other Cisco Unified IP phone, greatly simplifying IP phone management. This solution also can help customers and developers deliver more innovative and productivity-enhancing Extensible Markup Language (XML)-based applications to the display.

Cisco debug command

Debug is a troubleshooting command that’s available from the privileged exec mode of Cisco IOS. It’s used to display information about various router operations and the related traffic generated or received by the router, plus any error messages.
It’s a useful and informative tool, but you really need to understand some important facts about its use. Debug is regarded as a very high-priority task because it can consume a huge amount of resources and the router forced to process-switch the packets being debugged. So you don’t just use debug as a monitoring tool – it’s meant to be used for short period of time and only as a troubleshooting tool. By using it, you can really find out some truly significant facts about both working and faulty software and/or hardware components.

Because debugging output takes priority over other network traffic, and because the debug all command generates more output than any other debug command, it can severely diminish the router’s performance – even render it unusable. So in virtually all cases, it’s best to use more-specific debug commands.
