The business was at risk
More than a million phone numbers and customer voicemail depended on that platform. Without a replacement, we risked losing the core calling service the business depended on.
Negotiate and deliver a way forward
I negotiated a workable transition and brought carriers and delivery partners together around a replacement solution. I reconciled the number inventory and coordinated capacity for the move. Engineers and delivery partners built the new platform.
Keep a way back during the cutover
I required a carrier-by-carrier cutover, keeping both the old and new voice connections live so we could roll back if something went wrong.
I pushed for smaller migration batches against the vendor’s proposed schedule. With our core calling service at stake, I chose a staged move with a way to recover at each step.
Get the service onto a new platform
We moved calling service before the old platform closed and recovered the customer voicemail archive. I managed the transition and worked through cutover issues with our partners. The business had a path forward.
