We subscribed to teams subscription using: https://graph.microsoft.com/beta/subscriptions/XXXXX
This works fine. We actually do a patch to this subscription so it does not expire. Just change the expiration date. All good here. We have been doing this for some time without issues.
The odd thing is that yesterday we started getting calls to our subscribed method from teams calls that were repeated and some I even think are not ours. I think. For example we have a meeting that has 166 people and all are external users.... we have never had a meeting of this magnitude. I was not able to find in the team admin web page where I can find a team ID call to validate.
For every call we receive from the subscription we call the "https://graph.microsoft.com/beta/communications/callRecords/IDcall", this works fine and returns the details of the call. Curiously yesterday we started also getting the response "404", call not found. Even more odd as we are receiving the call from the subscription...so how can it not exist? Then we saw were where getting multiple call from the same meeting...repeated....repeated....
Did something happen yesterday? Did anyone see this behavior?
