Zero-Downtime Phone Cutover for a Disaster Help Center
How JetWave executed a seamless provider transition for a 300+ employee organization without interrupting critical community support operations.
Overview
A Disaster Help Center serving their local community with 300+ employees wanted to switch providers to capture improved service and cost savings. But because they support urgent community needs, they couldn’t tolerate any downtime during the transition.
JetWave executed a staged migration with temporary power supplies so the new phones could be installed and tested while the legacy phones continued running on PoE (Power over Ethernet). At the moment of number port + cutover, the organization switched seamlessly to the new phones and then disconnected the old system.

Improve Service Without Any Interruption
With over 500 daily calls and lives depending on every connection, there was zero margin for error.
Mission-Critical Operations
A disaster help center can't miss calls, continuity is essential for community support.
No-Downtime Requirement
They wanted the benefits of switching (service + savings) but only if operations could remain uninterrupted.
Hardware Transition Complexity
Rolling out new phones typically requires power/network readiness and careful sequencing to avoid gaps.
Parallel-Run Deployment with Temporary Power Supplies
To ensure a smooth cutover, JetWave built a plan around one principle: keep the old phones live until the new system is ready to take over.
Parallel Setup (New + Old at the Same Time)
New phones were installed and staged while old phones stayed active, ensuring continuous operation throughout the transition.
Temporary Power Supplies Loaned
JetWave lent power supplies so the new phones could be connected and configured immediately, even while the old phones continued operating via PoE.
Coordinated Port-and-Cutover
When number porting was scheduled, JetWave coordinated the cutover so new phones went live at the exact moment, with old phones disconnected only after successful activation.
Validation and Cleanup
JetWave verified all lines were operational on the new system before decommissioning the legacy infrastructure.
A Seamless Cutover with Zero Downtime
No Downtime During Migration
Calls remained supported throughout the entire transition, with no interruption to critical services.
Faster Rollout
By enabling new phone setup in advance, the actual cutover was quick and seamless.
Immediate Benefits
The organization gained immediate access to service improvements and cost savings from day one.
