Liberty-i

BT Wholesale SIPexpress

Carrier-backed SIP voice with a managed Liberty-i migration, configuration and support service.

01

Migrate at the right pace

Retain a compatible PBX, modernise the system, or move the complete voice platform in one controlled project.

02

Make every call path intentional

Numbers, routing, queues, handsets, apps and continuity are mapped before the cutover.

03

Secure the full service

Connectivity, firewall policy, permissions, monitoring and support underpin the voice design.

Carrier voice, delivered as an accountable service

Liberty-i uses BT Wholesale SIP services to support staged migrations from legacy lines and provide scalable IP voice connectivity. The service can be paired with a compatible existing PBX or a new Yeastar P-Series system.

Migration without guesswork

We document number ranges, call capacity, presentation requirements, emergency-service data, firewall changes and the cutover plan before any port takes place. Service options remain subject to compatibility and availability checks.

Your details are stored securely in the UK and are never sold.
