Cisco Unified Communications Reviews

• More reliable than other unified communication devices. • Lower cost of ownership. • It extends the video capability to your workers during a single, unified communications infrastructure from the desktop to teleprocessing rooms. • Interoperability and standards support. • It is scalable for up to 40,000 users. • It can be extensible to 80,000 users.

• One of the major flaws in the unified CM is handling the configuration of the Voice mail port. • Failure of higher call-control utilities such as transmit recall. • Failure of higher directory searching and call on utilities.

I have work on Cisco Unified Communication Manager (Call Manager) for one and a half years and it is a remarkable device which provides fully integrated communications, converging voice, video, and data over a single network infrastructure using standard protocols.
