# Thirdlane

> Thirdlane is a true multi-tenant, white-label unified communications platform for MSPs, UCaaS providers, ITSPs, and enterprises. It combines a carrier-grade multi-tenant PBX, an omnichannel contact center, Thirdlane Connect apps (web, desktop, mobile), a built-in CRM, native WhatsApp Business, AI voice intelligence, OIDC SSO, and S3 recording storage in one platform. Operators run it on their own infrastructure, in any cloud, or on Thirdlane Cloud, and sell it under their own brand.

Thirdlane (legally Third Lane Technologies LLC, founded 2004) builds the platform. It is Asterisk- and Kamailio-based, OpenAPI-first, and designed for service providers who want to operate their own platform and own the customer relationship rather than resell someone else's SaaS.
