Random calls to one extn

[danhole]

I have one extension which is receiving calls from random numbers, however, these do not show in the call log or events or activity log.

I have checked, there are no unusual phones registered, and the calls are not coming in via our sip trunk

is there anywhere else I can check?

If it's a STUN phone, and the port 5060 is opened, this is classic.
