Frequently asked questions
What is Thirdlane?
Thirdlane is a multi-tenant, white-label communications platform for MSPs, UCaaS providers, and enterprises. It combines a carrier-grade PBX, omnichannel contact center, Connect UC apps, a built-in CRM, and AI voice intelligence in one system you can run on your own infrastructure or have Thirdlane host.
Who is Thirdlane for?
MSPs, ITSPs, telcos, and UCaaS providers hosting voice and unified communications for their own customers, plus enterprise IT teams running communications for a single organization across multiple sites.
How can Thirdlane be deployed?
A provider can operate the multi-tenant platform on its own infrastructure or have Thirdlane operate it. MSPs and integrators can also deliver a dedicated environment for a single customer.
Is Thirdlane white-label?
Yes. Supported provider and tenant logos, names, and colors can be applied across selected platform and Connect surfaces. Custom mobile application artifacts and store-publishing assistance are separately scoped.
