01Migrate at the right pace
Retain a compatible PBX, modernise the system, or move the complete voice platform in one controlled project.
02Make every call path intentional
Numbers, routing, queues, handsets, apps and continuity are mapped before the cutover.
03Secure the full service
Connectivity, firewall policy, permissions, monitoring and support underpin the voice design.
A practical move to IP voice
SIP trunks connect a compatible PBX to the public telephone network over IP. Capacity can scale without replacing the whole phone system, making this a useful staged migration route.
- Retain a compatible PBX
- Port existing geographic numbers
- Add or reduce concurrent call capacity
- Plan diverts and continuity routes
Connectivity and voice assessed together
We check PBX compatibility, numbering, bandwidth, quality of service, firewall policy and resilience before migration. Final design and availability are confirmed during survey.
