You work as a systems administrator at YourDomain.com. Your company is planning to choose a Cisco Unified Communications solution because IP telephony solutions seems not be worth the cost. Which statement would be the best annotation to this concern?
A.
Cisco Unified Communications supports the idea of a converged network in which telephony and IP components are integrated, while the traditional office environments in which voice and data are separate.
B.
Cisco or its IP telephony specialized channel partners can customize these solutions to meet business demands and realize cost savings resulting from existing equipment or applications, while Cisco Unified Communications solutions are based on tested and verified designs that ensure rapid ROI.
C.
With low operating and capital costs, a Cisco Unified Communications deployment will pay for itself in 18 months on average, and will provide an average annual savings per user of US$334. The drivers of the ROI are determined by the unique network circumstances of the customer, such as the speed of migration, the remaining life on the PBX, and the extent of the data upgrade.
D.
An IP-enabled PBX inevitably reaches a point called the golden phone, at which an addition requires more than just a phone, but requires a card to support the phone, and possibly a new shelf of a cabinet to house the card. These upgrades end up being costly and offer the customer no flexibility to implement nonproprietary solutions in the future.
