Voice / PBX
Carrier-grade voice. Multi-tenant. Yours to brand.
The voice core of Thirdlane is a modern, multi-tenant SIP PBX engineered to scale to large customer bases. Everything from dial plans and IVRs to queues, recording, conferencing, and trunking — under one platform, one admin model, one upgrade path.
