On-premise business phone systems in Peoria

A switch in your building, when that is the right answer.

Cloud is not always the answer — bad internet, a hard compliance requirement, or a site that simply cannot go down. When on-premise is right, we say so, install it, and program it.

What comes with it

  • 24-hour emergency service

    A real on-call technician, not a ticket queue. Call the office and follow the prompts — any hour.

  • Guaranteed response times

    We classify faults as Major or Minor and guarantee a response time for both. In writing, before you sign.

  • Support that does not end at the invoice

    Ongoing support beyond installation and training, at no additional charge, through your warranty period.

  • Local shop, nationwide reach

    Based in central Illinois, with a nationwide network of certified technicians — so a second location is never a problem.

Serving Peoria, Pekin, Morton, Washington, East Peoria and Galesburg since 1987.
