2 published options covered. This is a selected shortlist, not every provider in the market. Research method and limits.
Swipe the table to compare all columns →
| Option | Published route | Before committing |
|---|---|---|
| One-Net Communications | Several UC/PBX platforms, cloud PBX and Microsoft Teams devices. | Request the proposed platform, hardware, installation and support scope. |
| Toku | A service connecting Microsoft Teams users to business calling. | Check the app or native-dialler option against your licences, numbers and calling costs. |
Choose whether you are replacing the phone platform or adding calling to Teams. Compare One-Net’s proposed UC/PBX setup with Toku’s Teams integration on that basis. List the users, numbers, call queues and locations first; device compatibility alone does not establish that the required calling or queue features are included.
These options are listed alphabetically. Compare the selected course, product or contract before committing; inclusion is not a quality ranking.
