What Global Call Forwarding does

Global Call Forwarding (GCF) is a cloud-based VoIP service provider operating since 1996 as a brand of United World Telecom L.C., a privately held Florida LLC. The company delivers virtual local, national, toll-free, and mobile phone numbers, call forwarding, SIP trunking, and outbound calling services to more than 8,000 customers across 160+ countries, with headquarters in Delray Beach, Florida and regional offices in Bangkok (APAC) and São Paulo (LATAM). GCF serves a mix of small and medium-sized businesses, mid-market, and enterprise customers, with named logos including Novartis, Allergan, and Crystal Cruises. The company is bootstrapped, has 30+ employees, and operates under founder Thierry Genoyer.

The platform is built on VoIP infrastructure with global PSTN terminations reached through carrier partnerships, configured via customer-controlled call routing rules and extended into enterprise workflows through integrations with Salesforce, HubSpot, Zendesk, and Microsoft Teams. In 2025, GCF layered AI capabilities onto the platform — AI Call Insights, call transcription, voicemail transcription, and sentiment analysis — shifting the product surface from pure connectivity toward analytics and conversational intelligence. The architecture is consistent with wholesale carrier interconnects and session-based routing rather than proprietary switching infrastructure.

The business model combines recurring monthly subscription revenue from virtual phone numbers, usage-based revenue from outbound calling and SIP trunking, and recurring revenue from premium feature add-ons, with managed services for enterprise accounts. Pricing is tiered by number type, country, and feature set, and the company sells directly to SMBs and through enterprise/commercial motions for larger accounts. Bootstrapped status and 29+ years of continuous operation indicate reliance on operating cash flow rather than external capital, with growth funded organically.
