Just an FYI in case anyone has encountered this.
You may have seen/received calls on your SIP device over the last couple of days (this isn’t limited to Trixbox, FreePBX, or A@H, by the way - this is anything that speaks SIP) with a caller ID of ‘John Doe <4000>‘. This does seem to be a world first - It’s someone, or something, actively scanning the entire internet for misconfigured SIP devices. There’ve been a lot of reports of this, as well as a lot of discussion on IRC. The most important thing is that most people don’t have anything significant to worry about. The second thing is that it’s going to happen again and again, as more people come up with this idea.

I thought of you folks and thought since I see no posts regarding this matter, I best inform you.
