Microsoft offers multiple paths to connect your system to the outside world. We guide you toward the right underlying connection for your office, existing contracts and technical setup.
Microsoft serves as the phone carrier, providing the numbers, public network access and emergency call screening directly.
Calls route through a certified third-party carrier, switched on easily from the admin center.
Connects any carrier through specialized network routing equipment run by the customer, an integrator or a provider.
Makes a user's mobile SIM number their Teams number, without supporting auto attendant, call queue or audio conferencing numbers.

Questions asked by local businesses
- Do we need a Microsoft 365 plan first?
Calling inside the company works on most Microsoft 365 plans. The phone license adds calls to outside numbers, and a separate Microsoft Teams license is required with every Teams Phone plan.
- What does it cost per person?
Published Microsoft prices are billed per user per month on an annual subscription. See the plans section above for current tier costs. CloudCentric installation is quoted separately.
- Can we keep our current phone numbers?
Numbers port from the current carrier onto your chosen connection route on a booked date. Old lines keep working normally until the port completes.
- Which desk phones work with the system?
Calls can be made from Teams-certified desk phones, meeting room devices and the Teams app on computers and mobiles. Yealink models handle everything from executive desks to warehouse walls.
- What happens to calls if our internet goes down?
Both phone systems need the internet connection to function. A second internet path requires separate equipment to keep calls routing properly during outages.
- How does emergency calling know where a person is?
Each user gets a validated emergency address. Dynamic emergency calling routes calls and notifies security based on where the client is at the time of the call.
- Where does CloudCentric install and support these systems?
CloudCentric is a managed IT provider in Mount Pleasant, South Carolina, serving businesses across Charleston, the Lowcountry and Savannah.
