My question is... security wise how would that be looking? We're a Cisco house, using Cisco VOIP phones, etc. I was under the impression that ARP poisoning, and man in the middle attacks, combined with Cain and Abel or another sniffer/translator program would make listening into the VOIP system rather easy. I just recently in my search came accross a Cisco white paper saying that having the phones on a different VLAN (even though the computers hook into the phones) negates man in the middle attacks.
So, please any thoughts, opinions, insights, or solutions would be highly appreciated.
