The politicians will only brag that they are doing good work in view of all the email they get. This sounds insecure, your next door neighbour seems to have all ports open and I thought VOIP was only deliverable to a specific IP address, but I suppose it must be vulnerable to man-in-the-middle interception if it's not tunnelled, gosh, another security hole. My only experience of VOIP has largely been on hamradio and I've never been able to hear anyone else's point-to-point, though I always thought the server would be capable of intercepting traffic. I once tried SIP landline to landline, but I couldn't hear the other send as my inbound port seemed set incorrectly.
VoIP is just that, IP ... there are a few ports involved, some compression and possibly some encryption although I doubt it, as its supposed to be peer-to-peer. When my uplink, which is a Cisco router/switch, functions as a hub it means that everyone connected to that device (my next door neighbour), will get ALL packets sent too and from my host, and I theirs. Very nice to know, isn't it...
