Teams Calls disconnect upon answering

Question

Hello

Please i need your help on this issue.

For the last 3 days we have had dozens of Teams calls that disconnect the moment we answer them.

The calls are not from the same number and when called back, We almost always get a pop-up message that the line is busy. 

Occasionally, we have gotten a customer or a caller, but rarely.

The screen shot attached is for a call that Karen one of our user answered. It rang once on her Teams phone, but the log shows that they called 3 times. 

The 22 second call is the one she attempted to answer.  The other two from this caller never rang on the Teams desktop App or Teams cell phone.

All the users linked to the call queue are all affected below

Hi @IniobongNkanga-8038

Please try uninstalling Teams and reinstalling it.

Please try disconnecting from the VPN.

If this issue only occurred recently (it was working fine before), please contact your administrator to report the issue in the M365 admin center or contact phone support for more detailed assistance.
