Solved Teams Presence Sync

[husseinharb]

Hello, We updated to V20 Alpha and love the presence sync between teams and 3cx. There is an issue. Teams set the user as away after some inactivity. this automatically sets the 3cx status to away and as you may know while on away mode in 3cx, phones or apps do not ring. what is a workaround to change this behavior? While on a teams Do not Disturb or busy, I understand that calls go to voicemail. But away is the problem. Thank you for your help.

Hello,
it's Sync only not Sync All, Does this affect the presence reflection?

Yes, add your extension .. and try.

My extension is already added

Is it still not working?
On the page: admin > Users, do you see a green checkmark at the far right end of the row for your extension?

If yes, click on your extension and go to the options tab.
Look for “Sync Calendars & Teams Presence.”

Is it checked?

Even after all that, is the Teams presence sync still not working?

RESOLVED


Analysis of Logs: I've observed that 3CX wasn't receiving any requests from Microsoft.
I conducted accessibility tests with the following results:

- https://[FQDN]/m365/notifications : Could not reach the page.
- https://[FQDN] : Could not reach this page either.

I suspected a restriction on port 443 in the firewall ahead of the PBX.
After requesting the removal of this restriction, the issue was resolved, and access is now functional and sync working.
