Microsoft Teams Voice Modern Workplace



The core business of CTELO is to assist our customers in implementing Teams Business Phone in the best way. Then users can intuitively use Microsoft Teams for all their communication needs. This is only achieved by making telephony a natural part of how they collaborate. Employees can stop thinking about how to act on a call, no matter where it comes from; the reception, a support number, a Teams colleague or someone calling in from a mobile phone. Teams become the one solution that handles all interactions. The users also need less training and can quickly start collaborating with others more efficiently. Our goal is to contribute to a more intuitive and communicative day.

We are proud to assist many small, medium and large enterprises in entering the collaborative era. By creating an efficient business communication environment, we support their success in reaching the market with their own great products and service offerings. Below you see what some of them say about us.

Microsoft Teams Voice Customer

Harald P.
Chief Systems Engineer

We had a lot of issues with Skype for Business telephony quality at a large global telecom provider.


Ctelo assisted us in moving to Ctelo Business Phone and changing telcos globally. Since then the service quality and support have been excellent.

Microsoft Teams Voice Customer

Kjetil K.
Manager IT Support

We have been a CTELO customer for many years, and as a public company, we are required to have public tenders for the telecom services every 3rd year. This time we had to change to a different telecom provider.


As Ctelo Business Phone users this was really easy. The change had no impact on the Teams setup or any cost.

Marcel O.
Manager IT & Information Security

Whenever a question or issue arises we know that the best competence is just an e-mail or phone call away.


The Ctelo team responds quickly to both Telco and Teams related issues that we experience.


This is why we chose Ctelo Business Phone and not a telephony service directly from a Telecom Operator.
