We no longer support the BT Versatility and BT Quantum phone systems. We stopped selling them, and support ended on 30 September 2025.
However, help is still available if you need it. We’ve moved our BT Versatility and BT Quantum help pages to the BT Business Community, where they’ll stay available. We won’t update them if anything changes with the products, but you may still get the answers you need from the BT Business Community.
Find your phone system below and view all the relevant help and user guides.
