Core offering

WPI Group (operating as WPINJ) provides international local geographical and toll-free phone numbers (DIDs), SIP trunking, and wholesale VoIP termination to cloud communications providers and telecom carriers across 50+ countries. The service collects inbound voice calls from local PSTN networks, converts them to VoIP/SIP via WPINJ-owned media gateways, and transports them over a private global IP backbone to the customer's data center. The three product lines are WPIDID (flat-rate DID numbers), WPI800 Toll-Free (per-minute inbound toll-free), and Outbound Service (per-minute A-Z VoIP termination), all managed through a real-time web-based provisioning portal.

All services are delivered through a private global IP backbone that interconnects local PSTN networks in 50+ countries, with a web portal for real-time provisioning and management. The company holds self-owned licenses and telephone number ranges, providing end-to-end control over its telecommunications infrastructure.
