        They don't, and people like ourself with Vonage-like services that interfaces with POTS are most definetely covered by the Do Not Call list. As far as them spamming my little VoIP box from Cisco - well, I may be a bit naive but I hope that it will only accept calls from my provider. If that feature isn't in already, I am sure it will be added days after voip spam starts.

      Existing VoIP services are through proprietary protocols controlled by the host companies (Vonage, Skype, etc...). Although the connections are made IP-to-IP, these clients are typically only built to accept connections that have been verified through the host network first. Although there have been problems with, for instance, instant message spam in the past, it is quite rare now (in my experience). Forging a message on a private network is much harder than on a public one.

      Spam is in the same class of social irritants as grafitti. (il mio Italiano no esta bonno).

      It is someone hijacking a lightly guarded public place for their own benefit. The physical area that gets defaced by grafitti is too low in value to hire a full-time guard to prevent its defacement. The shitperson can deface the area quickly with paint and not get caught, providing a free advertising medium for himself and his (always a male) message.
      Public law enforcement officers say that the faster an area that has been defaced by grafitti is cleared of the defacement, the less likely it is to be re-vandalized. I'm not sure if this applies to spam as well. However I do believe that spam in the same social catagory as grafitti.
      Spammers, like grafitti vandals, are assholes. To accept as legitimate advertisers is only to ask to deluged with endless amounts of worthless spam. The legal arguments that are used against vandals should be refined and tested in court against spammers.
      And, yes, grafitti vandals are assholes too. They aren't artists. They have the ability to create art but they don't. They foul public places. People who claim that grafitti vandals are artists are assholes too. So are the people who defend spammers as 'new media' advertisers.

      Meanwhile, spammers are usually already immoral people who have no respect for the law anyway. Viagra, afterall, is illegal to sell without a proper perscription, and a contact via web form is simply not good enough to generate such a perscription.

    Here's the wide open hole in VoIP phone service:

    Every VoIP phone that has a real-world phone number also has an SIP address that can be used to send calls to it as well... If those addresses get captured and traded around like e-mail addresses, then all a tele-spammer would need is the bandwidth and they're all set to call you with a spam-like ad.

    And the Do Not Call Registry law doesn't even apply because it registers phone numbers, not SIP addresses. So that and any other telephone-based law isn't going to work here.

          No, because while they all use VoIP, they themselves are not (yet) interconnected. Even if they were, the only call switch that your phone should talk to is the one hosted by your provider, since it is the determining factor as to where calls go, and all voice packets are routed through their network anyways.

          The individual providers still need a way to interconnect to all other providers, and currently the only way to do that is via POPs (points of presence) and SS7 trunks to the POTs network. Generally once traffic is determined to not be on the CLEC's local network, its passed out to whoever they connect to to handle outbound routing, be it VoIP or not. I doubt any serious LEC would use the internet as a major interconnect with another provider. The security risk alone is too much of a risk.

          Also note that not all providers currently use the same protocol (as has been mentioned in other posts), so even if someone spoofed a call from your provider, they would have to know how to talk to your phone, be it MGCP or SIP or something else.

          Just because your phone "has an world reachable IP address" doesnt mean it is wide open to attacks. I think the most serious issue to be dealt with will be DOS attacks, since most IVoIP (internet VoIP, ala Vonage.. as opposed to internal VoIP on private networks) cannot control their QOS between customer and callswitch.

    While legislation isn't the answer to spam, at least not wholely, if we start seeing people getting offensive voice mail spam the push on congress/FBI/etc. to put a stop to it will increase exponentially. You can always change E-mail addresses to avoid spam if it gets too offensive, but people aren't going to want to change their phone number and the spammers are far too greedy (and stupid) to realize they're crossing a line they shouldn't cross.

When John Doe Consumer starts getting racy, obscene and highly offensive voice mails inviting him to "gain 4 inches now" or "view barely legal teens" every day he's going to care a lot.

    A lot of the cheaper plans offered by VoIP companies, like cell phones, have a certain number of minutes you have per month. Some of the companies, foolishly, make you listen to an entire voicemail message before deleting it (in the cell phone world Cingular does this too), now if you have even 5% or 10% the amount of voicemail spam that you do email spam and you're forced to listen to entire messages before deletion this is going to take up a pretty significant chunk of your minutes... that's bad bad news.

      FYI: On my Cingular phone, 7 is the erase button after a message, but if you push 7-7 during a message it will stop playback and erase it. Don't know if it works on all phones/plans or just mine.

      Market forces tend to weed out these pratices. ATT had a consumer support problem. With number portability, they got the message something needed to change. When phone SPAM becomes too much and Cingular fails to keep consumers when the contract expires, then they will either change or fold. I love a free market!

      Not neccessarily. You could just have one free ENUM database and have all phones call each other directly.
      Many SIP phones are set up to accepts calls from any other phone. But phones would only ring if they see their own phone no/username.

      This is most certainly FUD.
      having the IP address of a VoIP phone is not enough to send them a voicemail. You have to know (at least on any decently secure system) a phone number, and an IP address. And, to leave a message you have to have an open communication channel with the messaging server, not the phone (again on any decently secure system).

      I manage VoIP for a 9000 node network. Only the messaging server can leave a voicemail in a persons voicemail box, and to leave a message on the system you have to open a connection to the server (over sip, or from the pstn) at any rate, if it was incoming spam to my organization it would have to come over the pstn (we are voip internally, to all of our branches, but pstn everywhere else). Thus, spam would have to be initiated from the PSTN, and would be limited to a total of about 200 simultaneous calls (we have about 10 PRIs for connections to the outside world, we run about 60% usage on those PRIs).

      Thus realistically a telemarketer could only leave about 80 messages simultaneously before starting to get the no circuits available error from our provider, and it would tie up 80 of their phone lines for the 30 seconds it would take to leave the message, and they would have to pay long distance etc for those calls. Now, inside our organization, you can send a voicemail to everyone at once, but it is very restricted (IE, you can only do this from 3 accounts, and to make a call from one of these 3 accounts you have to know the pin numbers to allow the call through).

      In our setup, I can't think of a single way to really automate sending everyone a voicemail, besides hacking one of those 3 accounts, or calling all 9000 people... granted you could have a voice recorder call the numbers, and leave messages, but telemarketers already do that, and with VoIP it would be no different. You can't just email the voicemail to the accounts, as the voicemail system only recognizes voicemail that it has put in the email accounts (it keeps a database of unique IDs that it puts in the email and only reads the emails it generated).

      Furthermore, emailing 9000 copies of a 300KB message, would require alot more bandwidth than sending 9000 4KB html viagra ads. Why would a telemarketer do it? Or a spammer? Bandwidth is cheap, but it still costs something. Sure, they can use their zombie nets, and then its not their bandwidth, but, if they are sending multi-megabyte chunks of mail, alot more people will notice that they are infected if their net connections noticably slow down.
    • Having read the article, I'm amazed that one very important fact has been almost completely overlooked - namely that every call will have a charge associated to it.

      Wrong.

      If the VoIP world goes the way of SIP (Session Initiation Protocol) then everyone will need to use a service provider to assist in routing calls outside of a business network.

When I first got married, my wife had that habit, if the phone was ringing, she ran to the phone to get it, even if she was busy. I always found that funny. If the phone is ringing and I'm doing something else, I don't answer it and let it go to voicemail. When I'm done, I'll check the VM and call back. Simple solution.

If you burn an extension for your front, rear, & garage door remote controls, you're still left with five valid internal lines to which you can connect a phone.

    Then your filter blocks every IP except the ones you know you want.

    Well this is interesting.

    Looks like it's time for homes to have small computers which runs a small voip routing server to handle calls of various natures:

    • A list of known numbers we trust.
    • Unlisted numbers to be dumped into a seperate bin
    • Voice to text scanning to determine content
    • Voice print scanning for known callers

    Sounds like an open source project to me.

    Also a great way to gather the numbers of known spammers and distribute a list of said numbers/ip addresses for blocking.

    The phone companies, as noted in the artcle, thinking that it isn't a big deal is basically shrugging responsibility for something which they should take more seriously. Given the nature of phone spam, email spam, and phone sms/messaging spam, to think that voip spam is a low priority target is pretty slipshod.

    *shrugs* Looks like voip filtering will just be an extension to the massive spam filtering already being done. Wish I could send a bill to the spammers for the extra work they are basically forcing me to do. :(
