OK, so you have decided it's time to replace the phone system that you have been using for ten years. What next?
I am going to make a bold suggestion...before you go to Google and start researching phone systems, talk to an experienced business telephone system sales person.
What's that? Talk to a salesperson? Are you nuts?
Hold on, and hear me out...
I have been selling business phone systems since 1989. In the past 22 years I have worked with thousands of companies implementing the systems that I designed and sold. I have seen most every problem and opportunity. To each new client, I bring that collective experience.
Now more than ever, you need someone who has experience to help you pick the technology that will improve your customer service, enhance your employee productivity, and lower costs.
A good sales person will ask you questions about your business challenges and goals. Then, drawing on their experience, recommend a solution. A good sales person will help you understand how the technology you are considering will benefit your business. And a good salesperson with manage to conversion from your old to new system and make sure you get the benefits you are paying for.
Finally, after you have the proposal in hand, then research the proposed system. The Internet is a wonderful tool to validate solutions that experts have suggested.
