## Frequently Asked Questions

### Who is the phone.systems™ Operator API for?

The phone.systems™ Operator API is built for businesses and operators who want to resell, embed, or white-label cloud PBX within their own service offering, not for individual businesses setting up a single company phone line, which is better served by the [standard phone.systems™](https://www.didww.com/tools/business-phone-systems) plan.

### Can I white-label phone.systems™ using the Operator API?

Yes. The Operator API supports co-branding and multi-tenant PBX management, letting you offer cloud PBX under your own brand name and interface while DIDWW manages the underlying infrastructure, call routing, and platform maintenance behind the scenes.

### What billing models does the phone.systems™ Operator API support?

The API supports multiple billing models, including per-seat, per-channel, and per-DID pricing, giving resellers and operators the flexibility to structure their own customer-facing pricing independently of how DIDWW bills the underlying service to you.

### Is there a sandbox environment for testing the Operator API?

Yes. DIDWW provides a sandbox environment that mirrors production functionality, letting your development team fully test integrations, billing logic, and multi-tenant configurations before rolling the platform out to live customers.
