One of your potential customers has concerns about choosing a Cisco IP Communications solution because, according to the competition, IP telephony solutions cost more than they are worth. Which strategy would be most appropriate to defuse this concern?

A.
Unlike traditional office environments where voice and data are separate, Cisco IP Communications supports the idea of a converged network where the telephony and IP components are integrated.

B.
An IP-enabled PBX inevitably reaches a point called the golden phone, at which an addition requires more than just a phone. In fact, it requires a card to support the phone, and possibly a new shelf of a cabinet to house the card. These upgrades end up being very costly and offer the customer no flexibility to implement nonproprietary solutions in the future.

C.
With low operating and capital costs, a Cisco IP 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.
Cisco IP Communications solutions are based on tested and verified designs that ensure rapid ROI. Cisco or its IP telephony specialized channel partners can also customize these solutions to meet business demands and realize cost savings resulting from existing equipment or applications.
