Dear All,

We have Skype for business server 2019 and excahnge server 2016. We have an issue last couple of weeks and some users recives fake missed call notifications. I checked message tracking and indeed our exchange server send the missed call notifications. User A never calls User B but user B recieve missed call notification. To be honest i dont know what to check, the only thing that i suspect is if the server has been hacked or something like this. We have also edge server for external user communications.
Could someone assist us on this?

Regards
Pantelis Komatas
