Number Portability in SprintHub

The number portability allows the customer to transfer responsibility for a landline or mobile number from a traditional carrier (Vivo, Claro, TIM, Oi, etc.) to a VoIP provider (VoxImplant, among others). In SprintHub, we do not carry out the portability process — we act as the call endpoint, integrating VoIP so you can make and receive calls directly on the platform.
Difference Between Registration and Portability
Purpose
Enable an existing number for use
Transfer control of the number
Responsible party
Customer (internal setup in SprintHub)
Traditional carrier ↔ VoIP provider
Approximate timeframe
Immediate (after setup)
3 to 15 business days (via ANATEL)
Involved parties
Customer and SprintHub
Customer, current carrier, and VoIP provider
Case 1: Registering the number in SprintHub
When the customer already has an active number with the VoIP provider and only wants to register it in SprintHub, follow these steps:
Access the VoIP module in SprintHub.
Check whether the SIP Trunk is configured on the platform.
Click on Add Number and select External VOIP.
Enter the number (landline or mobile) and the authentication details provided by the VoIP.
Save: from then on, you will be able to make and receive calls using that extension.
Case 2: Portability Process
If the customer wants to migrate the number from a traditional carrier to the VoIP provider, follow this flow:
Confirmation with the carrier
Contact the current carrier and ask whether the number is portable (rented numbers may not be).
If the number is in the customer's name and is eligible, request release for portability.
Verification with the VoIP provider
Confirm with the provider (e.g., VoxImplant) whether it accepts ported numbers from the originating carrier.
Start of the portability process
With both parties aligned, the carrier and the VoIP provider will submit the portability request.
The official ANATEL timeframe is 3 to 15 business days for completion.
Completion in SprintHub
As soon as portability is completed by the VoIP provider, return to the VoIP module in SprintHub and register the number as described in Case 1, now already "wearing" the new provider.
Final Considerations
SprintHub integrates your VoIP for calls, but does not directly manage portability.
Make sure the number is regularized and authorized by the carrier before starting the request.
After portability, treat the number in SprintHub as an external VoIP extension, following the standard registration flow.
With this clear and documented process, your company will have full flexibility to keep contracts with traditional carriers or migrate to VoIP solutions, always using SprintHub as the call center.
