Make it easier for customers to reach the right person.
Service scope
What we can plan with you
Build call routing around how customers reach your team. Discuss public numbers, queues, handsets, remote users and the process for transferring existing numbers.
Devices and users
Review desk phones, headsets and supported software clients. Include remote users and network requirements when assessing the proposed calling arrangement.
Transfer and handover
Check number ownership and porting details with the current provider. Coordinate the transfer and test inbound and outbound calling before retiring old equipment.
Choosing the right approach
Start with the requirement.
Then choose the setup.
Hosted voice can bring office and remote calling into the same arrangement. Mobile SIM-based business numbers may be more appropriate for some users; the options should be compared against how people receive calls and use their devices.

Fit the service to the way your team works.
A London business may operate from one office, shared premises or several sites. Clarify who owns the router, wireless network, internet circuit and Microsoft 365 tenant before deciding what your managed service needs to cover.
Your business voip brief should account for how people work, the systems they depend on and any changes you are planning. The points below help connect those requirements to the wider environment.
Shared and serviced offices
Establish which equipment and connections belong to the landlord and which are yours. Agree how faults are escalated when an issue crosses the boundary between building services and your own network.
Service planning: List current numbers and confirm ownership details.
Growing teams
Use a repeatable joiner and leaver process. Match accounts, devices, phone numbers and application permissions to job roles rather than relying on individual handovers.
Before making changes: Map call routes, opening hours and overflow handling.
