I have been asked to look at a interesting issue. BCM450 at head office with 5 VOIP trunks(Lines 1-5). BCM50 at branch office with 5 VOIP Trunks(Lines 1-5). The head office is getting hit constantly with calls on the 5 VOIP lines. Suspect hacker dialer. Calls are attempting to go back out of PBX but that is all blocked. I can see the calls on the BCM Monitor. When calls are coming into head office I also look at the BCM Monitor in the banch office and there are no calls on their VOIP lines. I can't locate where the calls are coming from. BCM450 has 2 T1's and 6 analog lines but monitor shows calls incoming on VOIP lines 1-5. Anyone with thoughts as to what I am missing. Thanks
