Case Study: Coffman Engineers achieves streamlined, centralized communications and built-in disaster recovery with RingCentral

Coffman Engineers Engineering Consulting Firm Communicates More Seamlessly with RingCentral

Coffman Engineers, a Seattle‑based engineering‑consulting firm founded in 1979 with 475 employees across 14 U.S. offices, faced growing problems from a patchwork of aging local PBX phone systems. Outages, rising maintenance costs, and limited features made communications harder as the firm expanded through organic growth and mergers, prompting IT to seek a centralized, easy‑to‑manage solution.

Coffman migrated to RingCentral MVP, consolidating all locations onto a cloud VoIP platform that simplified provisioning, enabled seamless call routing between offices, and built disaster recovery into the phone service by rerouting calls to other sites or employees’ home numbers. The change delivered operational benefits (plug‑and‑play phones, call sharing, Call Flip, built‑in conferencing), significant cost savings versus legacy PBX infrastructure, and reliable, proactive customer support.
