Ok, we have tested in a completely new Microsoft tenant and are receiving the same behavior on a manual rejection (pressing the big red button) on inbound calls to Teams. Once the button is pressed, the 603 Decline message is sent to the PBX and the call is dropped.I strangely hat this one morning after it had worked well for weeks. Once I started the desktop app, the issue stopped however when I only used the mobile app, all calls failed. MS Support to clear some cache in the app which did not resolve my issue while not using the desktop app in tandem. I removed on my iOS device the app and reinstalled it and 10m later all was back to normal. Would this fit your situation? Do you still have any other SBC configuration in your teams tenant?
We have tested with 3 different inbound carriers, just to rule out the carrier and now with a different Microsoft tenant. If this is normal behavior on the 3CX, I can accept that, but is a fairly large issue for our clients as most users are accustomed to pressing the red button if they don't want to talk with the person. Let me know if I'm missing something on the setup or on the 3CX. I feel that there is something simple that we missed or misconfigured.
