I led the move from an on-prem Mitel Connect phone system to cloud-hosted 3CX — exploring, presenting, purchasing, and implementing the new PBX for 160+ users across 10 locations, including remote workers, and cutting annual phone costs by 85%.
The On-Prem Phone Bill
The on-prem Mitel system was expensive to run and rigid to change, and it couldn’t gracefully reach the remote workers the business increasingly relied on. Cloud PBX promised dramatic savings and flexibility, but cutting over 160+ users across 10 locations meant the phones could not go dark.
What I Delivered
Cloud-hosted 3CX
Explored, presented, purchased, and implemented 3CX — a cloud PBX to replace the aging on-prem Mitel.
85% cost reduction
Cut annual phone-system costs by 85%, delivering immediate first-year return on investment.
160+ users, 10 sites
Migrated more than 160 users across 10 locations to the new system with minimal disruption.
Remote workers included
Extended the phone system to remote workers — reach the on-prem setup could never match.

The Impact
160+ users across 10 locations on a flexible cloud PBX, remote workers finally first-class, and an 85% smaller phone bill — real savings the first year and every year after.
From On-Prem to 85% Off
The most expensive phone system is the one nobody has re-examined in years. Moving from on-prem Mitel to cloud 3CX cut the bill by 85% and made the phones work the way a distributed business actually operates.
