Make it easier to stay in touch
Missed calls and unreliable connections frustrate customers and slow your team down. We help you review business phone systems, hosted email and internet connectivity, then choose an approach that suits your sites and working patterns.
Start with what is getting in the way: poor call quality, staff using separate numbers, limited bandwidth or difficulty working away from the office. We explain the options, costs and installation requirements before making changes.
Connect your phones, people and locations
We support hosted telephony, Microsoft 365 email and Teams, and business connectivity. Where continuity is important, we can assess backup connections and the services that depend on them.
For BASEC, CIS helped move business calls to Microsoft Teams as part of a wider Microsoft 365 project. Read the BASEC case study.
We plan migrations around users, number transfers and supplier dependencies, with a clear handover into ongoing IT support.
