Definity Systems cannot support the network needs of businesses.
This is blatantly wrong: Avaya Phone Systems designed Definity Systems specifically to meet the needs of businesses of all sizes. Smaller business will benefit from the Definity Server CSI, capable of supporting between 50 and 250 users on the network. For mid- sized and large business, there is the Definity Server SI, which can accommodate up to 500 users on the network.

Once you buy Definity Systems, youre stuck with it; Definity Systems are not able to grow with the company. You have to buy a whole new network in order to upgrade.
This myth is misplaced. Perhaps youre thinking of other companies, but all of Avayas products are scalable solutions; Avaya works with you to create a system that meets the needs of your company.

Avaya knows that companies change and grow; thats why Definity Systems can be upgraded without having to purchase a whole new system.

Definity Systems are a waste of money.
Definity is a smart financial move for two reasons: Avaya firmly believes in the idea of investment protection, allowing you to embrace new technology while keeping many of your existing components.

And, in the long run, installing a Definity Systems can actually save you money through Communication Manager, a powerful telephony software that helps increase productivity and profits.

Before Definity Systems are fully functional, you have buy a whole host of additional components and products, things I dont need nor want.
Nope. Definity Systems, like all of Avaya Phone Systems products, is designed to be an all- in- one solution. In other words, Definity Systems includes everything to help improve productivity and efficiency, without requiring you to buy additional components.

Additionally, Definity Systems are built along a modular design; as you upgrade, and as your business grows and changes, you only need to buy the components you need.

Definity Systems lacks the powerful features I need.
Not true at all: Definity Systems is powered by Avayas powerful, industry leading Communications Manager, giving you world- class telephony capabilities. Communications Manager includes over 700 advanced features that can improve the efficiency of your business.

Definity Systems also includes value- added applications like voice messaging, networking abilities, and call center.

Definity Systems only supports IP networks.
Very false. Definity Systems works with traditional and IP networks, as well as converged networks. Definity Systems supports business with a single location, and business with multiple locations.
