How to choose a business phone system provider

  1. Ask whether the system is cloud-hosted or installed on site, and who maintains it.
  2. Check internet capacity and backup: a cloud phone system stops when your connection does.
  3. Ask how 911 locations are registered for each phone and for remote staff.
  4. Compare per-user prices on the same features (call recording, queues, integrations).
  5. Ask for two or three references from clients of your size and industry, and call them.
  6. Get the scope, response times and price in writing before you sign, including how you leave and get your data back.

Questions to ask a business phone system provider

  • Is the price per user, and which features are extra?
  • Will you port our existing numbers, and how long does it take?
  • What happens to calls if our internet connection goes down?
  • How are 911 locations set up for office and remote staff?
  • Who do we call for support, and during which hours?
  • What is the contract length, and are phones bought or leased?

Yes, if they are within 50 mi of the Summit city center, our service radius for business phone system providers. Each listing shows where the IT firm is based and how far away it is. Proximity is 5% of the IFR Score, so a nearby IT firm gets a small edge.

Can business phone system providers pay to rank higher on ITFirmsRanked?

No. The IFR Score never reads payment status, and this ranking has 0 paid placements. Up to 3 Featured IT firms may appear above the list, labelled Sponsored and showing their honest rank.

What does a business phone system provider do?

Business phone system providers set up and support office phone systems, mostly cloud VoIP today: numbers, desk phones, call routing, voicemail and contact-centre features.

Can we keep our phone numbers if we switch providers?

In most cases yes: numbers can be ported to a new provider in the US and Canada. Keep your current service active until the port is complete, and ask the new provider to manage the port request.

What about 911 calls on a VoIP system?

Each phone needs a registered location so 911 calls go to the right place. In the US, multi-line systems must support direct 911 dialling and send dispatchable location information under federal rules (Kari’s Law and RAY BAUM’S Act). Ask the provider how they set this up.
