Receiving Calls on Android not ringing
Thanks Paul, this sounds like a bug for this particular device (Galaxy A03s). I have raised the Bug here:
Bug: Incoming calls not ringing on Galaxy A03s · Community (microsoft.com)
If you could
1.) Raise a support ticket via the Microsoft 365 admin centre
2.) In this thread put down the build numbers of the Teams App and the Galaxy AO3s
I will raise this to Microsoft engineering to review tonight. Of course, it could take a while to resolve but at least we are pushing it in the right direction. Thanks for providing all the information.
Hope this has answered your question
Best, Chris
Did anyone ever get to the bottom of this, any fixes? Just migrated my organisation to Teams voice, and this same issue has started to occur on some of the Samsung A23 phones we are using. Its worrying, as we use the Samsung mobiles as the walkabout phones, and confidence has been dented, as they are intermittently not ringing. The calls to our main number are supposed to simultaneously call the mobile Teams account. This worked very well in testing, but it seems the phone goes into some sort of sleep. It works again if you call the mobile account directly via Teams.
- In our organisation, through Intune/MEM/MAM policies we use PIN protection for the Teams app and also hide the content of notifications. Apparently, this was causing issues. Since version 1416/1.0.0.2024063901/0412 of the Teams Android App, it is very much improved for us.
The fleet of Android phones we are using are all locked down using the Managed Home Screen app (Android Enterprise multi-app kiosk mode). We discovered that the Managed Home Screen app must be set to 'Unrestricted' battery, in addition to Teams itself. This eliminated ~90% of the issues with our phones not ringing when called.
An underlying issue still remains though, despite all battery/power saving options being disabled for the relevant apps.
Microsoft have acknowledged that there was a bug preventing Teams from ringing when used with Managed Home Screen in early 2023. After providing them with bug reports they have commented that they believe the bug still exists and have asked for additional bug reports from our phones.
- The main issue remains that deactivate as much as possible any feature that saves battery consumption (no daily automatic optimization, no adaptive power saving, exclude Teams from going into sleep model and/or disable "unused apps to sleep", exclude "android wifi services" from battery optimiszation ....). After all that, seldom that these problems still occur
robnicholsonmalt That's a really good shout, but unfortunately the user the calls comes into from pstn, is a standard user setup on desktop phone. So we don't see that setting, if it even exists for standard users .... We only really need it to ring on the two devices simultaneously, but it may be related to presence I'm guessing
