      First - almost all residential VoIP customers still are using analog phones. You plug your analog phone into a device that converts analog signal to IP. So you can't fubar an analog phone with a virus or send spam to it... it's just impossible. Could you fubar the converter? if you have no firewall or router - maybe with like a DoSS attack. But it won't accept random connections from another telephony device not registered with your telco's IP PBX

      Second - every voip customer still has a regular phone number - 202.555.1212 or whatever. in order to reach me on my "VoIP phone" - you have to dial that number. You don't dial my IP address!! You dial my phone number, which goes to a T1, plugged into a Telco's router that sends the packets to my house that get converted from IP to analog by a device sitting behind my router/firewall. So everyone from the outside wishing to get to my "VoIP phone" needs to dial the number, just like any other phone.

      Third - if you really have IP Telephony (not just VoIP, cause there is a big difference) you are only vulnerable to people on your same LAN/WAN - in otherwords someone needs access to your private network. And even then, they would need to register a device with your IP PBX and then trick it into letting you send pre-canned voice calls. In otherwords, this isn't possible. I'm sorry, it's just not.

      If the entire POTS system goes away, and we all have IP phones and there is no more telephony as we know it and all our phones are on one giant, unprotected, unfirewalled network, then yes, you might be subject to SPIT. But I assure you, this won't happen for a long long long time. /rant

For example, suppose my phone will only look at incoming connections which are begun with some certificate signed by the VoIP service provider (Vonage, Skype, whatever). So, in order to be able to call me, your phone first contacts the provider, requests a certificate to connect to me, and the provider gives that to the phone, and then their phone uses that as credentials to get my phone to not ignore it. Then, all the service provider has to do is watch out for excessive numbers of connections coming from one customer.

    I wouldn't be surprised in the least if this isn't already built into the VoIP systems. After all, we've been trying for some time now to move email into the domain of cryptographic authentication (SPF is just an intermediate fix) to stop spam.

    • Protocol enforcement techniques such as greylisting. Greylisting tests that the sending host is willing to make the effort of retransmitting, as required by the protocol.
    • Content filtering. Even a server-side antivirus program is a content filter; much more so the statistical filters often used today.
    • Multi-site statistical tools. Vernon Schryver's DCC and Vipul's Razor come to mind.
