Case Study: Colburn Construction Inc. achieves 85% lower phone costs and smarter call routing with Ooma Office

When it pays to get the calls that matter most, Colburn Construction calls on Ooma Office

Colburn Construction, a union-affiliated contractor based in Cullman, Alabama with more than 200 employees and a four‑person main office, was hampered by an outdated phone system that rang every desk, produced frequent telemarketer interruptions, lacked key features, and cost more than $300 per month—creating inefficiency for a small team that manages projects nationwide.

By switching to Ooma Office, CCI added an automated Virtual Receptionist, professional greetings and extension dialing, and a self‑managed setup that routes callers to the right person and blocks unwanted calls. The result: faster caller routing and fewer interruptions (telemarketer calls roughly halved), a more polished public persona, and a drop in monthly phone costs from about $300 to $40—over an 85% reduction that boosts the company’s bottom line.
