Unidentified Incoming Call

[TLCtech]

Since 4:30pm yesterday, we started getting these warnings, and its every couple of minutes since 10:09am. Below is one of the warnings. They vary slightly, but all are titled the same. The IP address seems to be DigitalOcean, the host provider 3cx uses for its hosted products, as I understand it. As far as I can tell, calls are coming through just fine. Any idea what this might be?

This call seems to come from an unrecognized source and it was rejected from the PBX. You may also check the event log guideline here.

Sounds like its doing its job then.

 

[TheodorosG_3CX]

Yes correct, those calls are rejected as they are not recognized from the PBX and will be blocked.

I have this issue as well, but with actual legit calls being thrown away. Is there a way to change a setting so that it will let those calls through?

Why unauthorized calls should not be rejected from the PBX?
