Using Microsoft Teams as Your Business Phone System
How Microsoft Teams Can Power Business Voice Communications
Using Microsoft Teams as Your Business Phone System
October 26, 2026
COVID changed the way a lot of companies work. Some employees have returned to the office full time, but many businesses are now hybrid and others have employees working entirely from home.
That has also changed what companies need from their phone systems.
For many organizations, Microsoft Teams is already part of the workday. Employees use it for meetings, chat and working with colleagues whether they are in the office, at home or somewhere else.
Teams can also be used as the employee’s business phone.
Your Business Number Can Go With You
With iTeraTEL voice service integrated with Microsoft Teams, employees can make and receive regular telephone calls through Teams using their business number.
They can take those calls from the Teams application on their computer, and the Teams mobile app gives them the same flexibility when they are away from their desk.
A customer calls the same business number. The employee can answer in the office, at home or on their mobile device without giving out a personal cell number.
What About Your Existing Numbers and Phone Features?
Moving calling into Teams doesn’t mean giving up the telephone numbers your customers already know.
Existing business numbers can be ported and connected to the Teams environment. Businesses can also continue to use familiar features such as auto attendants, call queues and direct numbers.
You Don’t Have to Get Rid of Every Desk Phone
Teams calling doesn’t have to be an all-or-nothing decision.
Some employees are perfectly comfortable using a headset and Teams. Others still prefer a phone on their desk. Reception areas, warehouses, common areas and meeting rooms may also be better suited to a physical phone.
A business can use both.
iTeraTEL can integrate business calling with Microsoft Teams while continuing to support physical IP phones where they make sense.
The goal is not to change the way people work just for the sake of changing technology. It is to give employees a business phone solution that works wherever they are working.
