Case Study: Hawley Troxell achieves PBX-to-cloud migration and mobile, reliable calling with Zoom Video Communications

Hawley Troxell’s Journey from Legacy PBX to Zoom Phone

Hawley Troxell, Idaho’s largest full‑service business law firm with more than 70 attorneys across multiple offices, was held back by a 15‑year‑old on‑prem Mitel PBX managed by a long‑time MSP. The aging system made licensing, security updates and remote phone deployments slow and cumbersome, required firewall workarounds for remote users, and limited the firm’s ability to manage telephony directly.

The firm migrated to Zoom Phone, leveraging its existing use of Zoom Meetings for a smooth evaluation and rollout. Zoom Phone provided intuitive softphones, centralized admin control, plug‑and‑play provisioning for home and mobile devices, and an API used to export call logs for accurate client billing—resulting in fast adoption, improved mobility for attorneys, simpler IT management, and more reliable, modern communications.
