I have setup a Group Number and 6 people in a call group that should ring at the same time and they should all be able to answer, all devices ring, however when someone answers with a mobile Teams app, there is no audio. so I have been testing a few days and found out if I bring the call group members down to 4 users then when they answer with mobile teams app on Android or IPhone all works fine, as soon as I add 5th person to the Call Group Audio doesn't work on the Mobile App, but it works on their PC app and a SIP device that its been setup too.

I have researched and there is apparently a limit of 25 per call group so why is this happening for 5 people in the call group? any help workaround ideas would be appreciated.

I have also tried changing from Call Group to delegated and as soon as I go over 4 users the audio stops working .

    Hi @Souren Dadaian

    If the order in which call group members receive notification of incoming calls is set to Sequential, the call group cannot have more than 5 members.

    According to your description, this problem only occurs on the Teams mobile client. Please try to update the Teams mobile client to the latest version or uninstall and reinstall it.

    You can also contact your administrator to report the issue in the M365 admin center.
