Do you need a business phone system?

How will your current system function as your grow?

Sure, your current phone system may work for you now and it may have always worked for you in the past but how will it adapt to your business growth? Will you be able to scale and add more users, lines and features easily or will your current system provide an obstacle for business growth?

Vonage is designed to scale freely, meaning you don't have to worry when you need to add more users.

If you have lots of mobile workers, what type of impact is that having on customer service?

Any modern business needs a phone solution that provides an effortless method for customers to get in touch. Vonage provides a solution that makes your business look centralised and established. Features such as Shared Lines and Call Forwarding make your remote workers appear to be in the office and easily contactable.

Traditional phone systems don't allow the freedom of a cloud based PBX.

Are you aware of how your phone service can impact service perception with your customers?

Extensive analytics allow you to see how calls are being received and more importantly, missed. Your current phone system may be letting you down and if you don't have extensive reporting features you won't know if you are losing potential customers.

It's time to empower your business.
