on Google

  • Your numbers stay yours.

    Ported on a date you approve, with the old line live until the new one is proven.

  • Calls ring where they should.

    Built around how your office actually answers.

  • Phones and network, one company.

    Nobody to point at but us.

Know what is in the phone bill.

What you pay for

Lines. Seats. Extras.

Separate the service from the add-ons.

What you need

A system that fits.

The right capacity, features and call routing.

We review the existing bill, the way your people handle calls and the features you actually use. Then we compare the full cost, including service, licensing, equipment and any changes needed.

Phones, start to finish

  • Calls go where they should.

    The main menu, which phones ring, what happens after hours, and voicemail in your inbox, built around how your office actually answers.

  • When the office goes down.

    If the internet or the power drops, calls can ring your cell phones, or go to a general voicemail if you’d rather your cell stay quiet.

  • Porting your numbers.

    You keep your numbers. We untangle the carrier account first, then port them on a date you approve.

  • Before we switch.

    We check that your internet can carry the calls. Desk phones that are compatible get reused.

4 more things we look after
  • Staff on the move.

    The office number on a phone app, so nobody hands a client their cell.

  • The odd lines too.

    Fax, the postage meter, the elevator: the lines that usually mean paying for an old copper phone line. Covered.

  • Call quality.

    We run the phones and the network, so a bad call gets someone looking at the traffic instead of two vendors blaming each other.

  • After hours, an AI receptionist if you want one.

    It answers what a good receptionist would and puts callers through to a person whenever they ask. How we set those up.

Switching IT companies in the middle of a phone cutover?

Switching to us

An hour without phones is the expensive hour.

Email can wait an hour. The internet can limp along. The phones cannot. Customers hear nothing and try the next name on the list, which costs more than almost any other outage.

So a phone outage goes to the front of our line.

Including when you call us about the phones. We pick up.

How a cutover goes.

How a cutover goes.

  1. The new system goes in first.

    Built and ringing before anything moves.

  2. The port happens on a date you approve.

    The old carrier stays live until the new line is proven, so callers should not notice the switch. Phone projects go wrong when the main number turns out to be parked in a carrier account nobody has logged into since the last office move. We untangle that first.

  3. Then we stay on it.

    The first weeks turn up small call-flow changes. Ask, and they get done.

The new phones ring before the old line moves.

What clients say

Awesome service and very quick response when needed. I would highly recommend BDunn.
