The challenge
Per-country regulatory paperwork, mismatched LOA formats across the four legacy providers, and a strict no-downtime requirement on the live numbers.
Our approach
Tiered the markets into strategic, coverage and long-tail. Standardised the LOA template per losing carrier. Provisioned the new ranges in parallel with the porting workflow so the receiving end was always ready.
Outcomes
- 147 local DID ranges live in 21 calendar days.
- Four legacy carriers consolidated into one direct-to-customer billing relationship.
- Zero customer-visible outage on any of the migrated numbers.
- Internal porting effort reduced by an estimated 70% versus prior quarter.
"The number we cared about was the days from kick-off to coverage. Twenty-one beat our internal estimate by three weeks."
