Communications (CPaaS)

Carrier-grade voice routing, messaging, notifications, fraud control and media.

The communications plane: least-cost voice routing with SBC, SIP, STIR/SHAKEN and WebRTC; value-added services (voice apps, USSD, ACD, subscriptions); multi-channel notifications with SMSC and OTT; telecom fraud and revenue-assurance controls; and a media plane for transcode, packaging and DRM-gated playback. This category cross-links to the dedicated CPaaS portal.

Auth is one model across every service here — an SS-01 bearer token plus X-Tenant-Id on every /api/v1 route. Public base https://api.nexocloud.io/api/v1.

5 real backends, 190 operations.

Every path below is a real route from services/<svc>/openapi.json. Each service lists a representative slice of its full contract.
