We are launching a new service that lets you connect your Microsoft Teams users (any Office365 organizations out there?) to FreePBX. https://simon.tel/2020/07/teams-calling-for-freepbx/
Simon Telephonics Teams Gateway connects Teams clients to FreePBX as normal extensions. This isn’t a managed phone service or PBX; it’s a connector so that you can use Teams with your own FreePBX the same way you would use any extension.
A major benefit of Teams in this role, other than direct integration with the existing Office environment, is secure, encrypted calling both on the desktop and on mobile.
You can see Teams and UCP calling each other in this Youtube video: https://youtu.be/hyYk6sR9Eko
Let me know if you’d like to try it free for a month.
Normally we are in the mode of sharing free advice and solutions on this forum, and I recognize that. You can build a do-it-yourself Teams SBC! I have seen a lot of discussion on mailing lists related to other open-source VoIP software on this topic. However, it is not for the faint of heart, which is why I think some folks might be interested in our gateway service.
Feel free to reach out on this post with questions, opinions, criticisms and the like.
