Saw this in the event log of our VCS. Seems as if someone is querying the VCS with fake identity. What do you think?

Thats exactly what it is. You can setup a call policy though to deny this.

Its two things,

* there are ways to use a CPL to block these kind of calls we discussed that earlier, like in:

* but if he has a call loop it might be interesting if he has some search/transform rules coursing that.

I could assume its most likely towards his traveral zone or the dns zone.

Its interesting to look in the search history of that call or a signaling trace to see what's causing the loop.

Regards DNS loops you find some info here:
