`There is an interesting bug in a Mitel's servers for Voice over IP that allows to discover the numbers called and the numbers calling trought this dhcp server. This server is configurable via http interface and via telnet; in this case, if there is a call at moment of login/pass request, I've noted this:

So, it's too easy to know the telephonic's "movement" inside a lan that use this fucked system of VoIP.
