Forever Free 3CX APIs by Mr. VoIP

Building reliable APIs usually isn't cheap, which is exactly the barrier Mr. VoIP's forever-free 3CX API suite is meant to remove. The set covers the calls most customizations actually need — Make Call, Pickup Call, Start Call Record, Drop Call, Add Agent, Query Extension, Add Queue, Update Queue, Delete Queue, Change Recording Status, and Disable External Call — with no upfront cost or commitment attached.

It's open to both 3CX customers and resellers who want to build custom features or integrate with existing systems without staffing an in-house development team. Sign up and you'll get setup instructions along with access to the documentation and knowledge base — or contact us directly if you'd rather talk through what to build first.
