Vonage Says VoIP Traffic Blocked By Providers

Anonymouse writes "Advanced IP Pipeline reports that Vonage has filed numerous complaints with the FCC over their VoIP traffic being blocked by major providers, something providers have long worried about but had not yet been seen 'in the wild.' Analysts expect the issue of network neutrality (or network discrimination) is only going to get larger as the bell and cable companies expand their VoIP efforts and bump heads with smaller providers."

      ISPs are most explicitly NOT common carriers!

      Under US law, as interpreted by the FCC, ISPs are engaged in "information service". This is a service rendered atop underlying "telecommunications", which, if provided as a "service" (for a fee), would be common carriage. But what that means is that ISPs usually buy their bandwidth from common carriers. (They can also self-provision, as via wireless, or when a cable companies provides it over its own wire. Then there's telecommunications without common carriage.)

      ISPs, as information services, are expected to do more than pass along raw information. Indeed one of the legal justifications for their being treated a "information" rather than "carriers" is because they do have the right to pay attention and sometimes do. Spam filtering, address-range blocking, virus filtering, pr0n filtering, etc., are all "information processing".

      Now along comes VoIP. It flaunts its non-common carrier status. Vonage got an FCC ruling (now being appealed by state regulators) that it is not a telephone company subject to common carrier rules (and taxes). The logic basically goes like this:

      - Telephony is common carriage
      - IP is usually used to carry information
      - Information is carried above common carriage
      - VoIP is carried inside IP packets
      - Therefore VoIP is information, not telephony.

      If you look carefully, you can see why the states are upset. As an analogy, assume that postmen wore gray suits and policemen wore green suits. If a postman put on green trousers, could he give you a traffic ticket? (There's a minor technical flaw in their reasoning, because Vonage-type companies actually interconnect with the telephone network via regulated, taxed telephone companies. But they don't always play by the same rules.)

      Still, the point is that ISPs are not common carriers. Vonage and other parasitic VoIP service providers (that's a technically-correct description, not an insult, because they take advantage of ISP and telecom services already paid for by their customer) don't pay like telephone companies, and have to adapt to the underlying transport (ISPs), to whom they pay nothing. So if the ISP wants to block them, it's perfectly legal. Your recourse is to change ISPs. Telephone companies pay for their wire. It shows up in the price.

      Now here's the catch -- what choice of ISPs do you have? Cable companies don't usually offer choice, or else usually only offer two (themselves and maybe one little-advertised option). Telco DSL is technically a common carrier telecommunications service that has to offer service to any ISP that asks; Verizon Online is supposed to be just another ISP to the Verizon Telephone Companies. That's why Speakeasy can run over Verizon wire. However, Verizon and BellSouth have petitioned the FCC to drop all of those rules. They want to not be common carriers, and want instead to use their wire to carry their own ISP, period, no choice. See the FCC's web site, e-filing, ECFS, Docket # 04-405 and 04-440. As "self-provisioned ISPs" (like cable companies), they would be allowed to block Vonage freely, and deny you access to competing ISPs. This is what the Bush FCC appears to have planned for you.

      Vonage is limited to using standard IP QoS, since it is just a regular IP device. However, an MTA built into a cable modem has full access to the cable modem QoS code. Part of the DOCSIS specification states that a DOCSIS 1.1 cable modem must support multiple "service flows", which are basically different queues. Each of these queues has it's own classification parameters (i.e. drop packets, forward packets, QoS, etc.), so it is only natural that a cable operator would give voice calls through their MTAs a higher QoS.

      Where Vonage calls might get screwed is because the packets that are being sent through the cable modem by the Vonage MTA would be considered as data, and would go out through the data flow. If the cable operator so chose, they could configure the voice flow to work with the Vonage MTA, but whether or not they'd do that is another story.

      You dont understand how SIP works.

      VOIP calls run exclusively over UDP packets. There is not a TCP packet to be found. SIP, or Session Initiation Protocol is a UDP handshake that is used to setup a connection. With consumer VOIP circuits, the client will send a SIP registration request to the SIP proxy server (Vonage in this case). The proxy server will reply with an OK. The actual payload of the UDP packets looks just like an HTTP transaction (complete with a GET and headers) and ditto for the reply. It is just not in a TCP stream. If a packet gets lost, then it is lost and the transaction does not happen.

      The SIP client will nearly continually repeat this UDP registration followed by shorter "keep alive" exchanges. The idea is to keep any NAT router happy so that the channel now is end-to-end connected.

      If the server needs to ring your phone, it now has an IP address and UDP port number that it can send a packet to. This then causes the SIP client to setup an RTP "connection". Again, these are UDP packets and TCP is nowhere to be found. The RTP connection is basically a set of UDP packets sent out very quickly. For a non-compressing codec (like G711.u [aka ulaw]), this means 50 UDP packets/second of about 220 bytes each. The packets go both ways at full speed (which is why VOIP does not work over dialup). There is no error detection. If a packet is lost, 20ms of voice is dropped.

      So is a SIP client a server. I don't think so. I think it is wrong to describe a server as something that listens on a port. In the case of residential internet access, it is not the listening that the ISP does not like. It is the bandwidth and usage patterns. A better metric would be "is this a one to one communication". A web server is one to many. Ditto for streaming video. SIP is one to one. If you want to call SIP a server, then you should probably call an IM client a server as well.

      What the ISPs are really doing is trying to figure out how to charge some people "more" when they can get away with it. It is not just "usage", but also an arbitrary categorization of what is residential access. From a purely network and traffic point of view, bittorrent should be the first thing outlawed.

If this is not against the law, then the law should be enlarged to stop the practice. At the very least, this policy should be openly disclosed by the ISP to all of their customers up front.

In the IP sense, a traditional telephone is a "server", because it is always listening on the line for the voltage wiggle that signals an incoming call. An IP phone has to listen for incoming connections; this is done by calling the listen() library routine. The term for such a program is "server". If an ISP doesn't allow servers, they are intentionally blocking things like IP phones.

      The common ISP "no servers" rule is equivalent to having a telephone line that only allows outgoing calls. That isn't very useful, of course, though phone companies can sell you that sort of service if you want it. They can also sell you a "server only" service that only allows incoming calls. This is actually a bit more common, though still fairly rare. You don't see many phones set up these ways, because people normally understand how useless such a phone would be to them.

      The main reason that ISPs have gotten away from this is that the Internet reached popularity with the idea of "web browsing". This led to people accepting the idea that a web site was something that someone else did, and you just looked at them. But the real value of the Internet is two-way communication, just as with the telephone. You shouldn't have to relay email through a third-party site, any more than you should have to use voice mail to send someone a telephone message. You should be able to make some of your own files available on the Web, by running a web server on your machine. Not allowing such things is as limiting as an outgoing-calls-only phone line would be. You have a pale shadow of an Internet connection, and are missing some of the Internet's most important capabilities.

      It'll probably all sort itself out in a few more decades, and we'll be able to use the Internet as it was designed. But we're seeing one of the battles here. The big companies want their control back. They don't like these little upstarts providing a comm service. If they can get away with it, they will block traffic to and from their competitors, so you'll have to pay them extra for a service that your own computer could do on its own.

      Apparently you have some misconceptions of how SIP works too.

      The latest SIP RFC (RFC 3261) *requires* (in normative text) that all devices support both TCP and UDP as transport protocols. SIP devices MUST use TCP as a transport mechanism if the message to be sent is within 200 bytes of the MTU of the transit link.

      Also, SIP has no "GET" header (like HTTP). The SIP methods defined by RFC 3261 include INVITE, REGISTER, ACK, BYE, CANCEL, and OPTIONS. Other subsequent SIP-related RFCs include other methods such as PRACK, SUBSCRIBE/NOTIFY, INFO, and UPDATE. These are all well defined and the RFCs are publicly available.

      I agree with the parent poster that SIP devices should be considered servers. I'd go one step further that the RFC defines a PEER TO PEER protocol, where all SIP devices MUST act as both clients AND servers. If I call you, my request is made from the "client" aspect to your "server" aspect. Once the call is setup, if you hang up the phone, your BYE message is sent from your "client" aspect to my "server" aspect. This is the nature of SIP.

    At the time, you had to jump threw hoops to get Vonage to turn ON compression and reduce the network loading by a factor of 10 to 20x, (down to 4 to 8Kb/sec). But at the time, activating compression was a double edged sword, as quite a few of Vonage's termination switches&gateways no longer worked properly with the compression protocol activated.

    Since then, they have improved things a bit. They've added a user configured "Bandwidth" saver to the account management web page, and "Probably?" fixed many of compression issues with the termination switches&gateways.

    But from what I hear, the nasty (2 * 80Kb/sec) is still the default, and it inflicts a "Tragedy of the Commons" type problem on smaller ISP's. Where no single user causes a problem, but when dozens/hundreds of simultaneous users start placing calls using their Vonage service, an ISP with limited resources is forced to act. This problem can only be corrected at the source, (Vonage), since most users are blissfully ignorant of the implications. (I.E. A couple of intelligent users reseting their compression settings will have little net effect on the overall traffic patterns. )


    In summary, Vonage is complaining about smaller phone companies not providing enough IP bandwidth to carry a significant portion of their PAID/Measured traffic over Uncompensated long distance backbone connections. Ha, fat chance! For the most part, I would say that Vonage's problems are self inflicted, story over.

    Basically Vonage and Co are zombies and they will rot away in a the next 2-3 years. As Don Corleone used to say "Nothing personal, just business"

    Not gonna happen.

    The correct assumption is that the traffic is not blocked, but assigned to a low priority class and throttled.

    That would be pretty stupid and neanderthal, too. It can't be done in secret. The first technician who is hauled before a Grand Jury is going to give up his managers in a heartbeat. The first manager hauled in will give up the droid suits in a heartbeat. The droid suits will be indicted. I imagine they're stupid enough to try it until a few of them have been consigned to the graybar hotel for a few years.

    Vonage has over 350,000 "lines" and is adding them at 30,000 per month. The genie is well out of the bottle and can't be put back. VoIP growth is now running at 900% per year. Shipments of VoIP switch equipment have surpassed shipments of traditional switch equipment. The avalanche is well underway and people who have tasted affordable, flat rate VoIP service that works from almost anywhere on the planet are going to be out for blood if any politician, bureaurat or weasel telecom tries to get in the way.

    I invite any telecom droid who wants his career to turn into a blackened, smoking pit to just try messing with VoIP traffic. Expect existing laws to be stretched to cover this and expect interference with VoIP traffic to be criminalized very soon.

    To me it seems that lack of competition between telcos as well as between network providers (ISPs) is a large part of the problem.

    I live outside the USA, in the somehwat tiny country called the Netherlands. Where I live, I have a choice between at least 3 telcos, at least 5 DSL ISPs (using one of the 3 telcos, and one offering the alternative of cable)

    My ISP started years ago as a 'free' internet provider, and is in fact a part of one of the 3 telcos. Now, I happen to use some other telco, but can still get their services (and DSL) despite it not going through their own lines.

    They just upgraded my connection to 8mbit down and 1mbit up, give fixed IPs, allow running servers explicitly (not unusual overhere actually), have a fair use policy, but despite using 100s of gigabytes/month I have yet to run into the limits of that policy. They are also not an exception here, and competition forces them to keep this up.

    The interesting thing is that part of this is a consequuence of government interference, specifically, forcing telcos to carry DSL for any ISP and not just their own.

    The telco that my ISP belongs to has to allow others on their network, but in turn, their ISP is also allowed on the network of other telcos, so in the end it evens out nicely ad both have the possibility to deliver services quicker and with less investement.

    Regulation that serves a clear purpose and is implemented well can do a lot of good for an otherwise free market, and can in fact make that market more free.

    I know that doing it yourself is the American way in this, but on behalf of its citizens, the overnment could in theory do a lot of good here.

    If a broadband ISP can't handle all their users utilizing 160Kbit/sec of bandwith they are far too oversold to be of any value to any consumer.

    I work for such a provider, and we're also a Old School Long Distance(tm) company. If we were to block or limit wanted traffic (VoIP service), we would be breaking the statutes that allow us to remain common carriers of IP traffic.

    Even to deal with virus outbreaks, we don't stop the packets (that would be filtering, which is bad), we just redirect them to a device I have built that can identify the customer from radius logs and network maps, then spits out a report for us to contact them.

    Common carrier is important, and there is court prescidence to justify the fact that 'rate limiting' is the same as 'filtering' in the eyes of common carrier status. Let someone take it to court against the provider, then there will be hell to pay. Would you want to be "responsible" for the data passing over your internet connection?

    Thought not.

    The article states:

    "According to Powell, his understanding is that the blocking is not coming from major service providers, but from rural Local Exchange Carriers (LECs). Brooke Schulz, Vonage's senior vice president for corporate communications, said Monday that the company would not comment on the report."

    From that it sounds like it is certainly the phone companies not the ISPs that are blocking the Vonage traffic. This probably means that they *are* common carriers. However the article states there are currently no laws regarding this type of blockage. But, I repeat, "this has nothing to do with the ISPs"!!!!!!

    The argument that LECs and ISPs have been using to avoid liability for filesharing is that they are not content providers and have no responsibility to filter or otherwise regulate the content that is delivered over their links. However, once they start filtering VoIP, then they are implying that they are indeed making an effort to regulate content, and therefore are opening themselves up to more legal nightmares.

    The only problem with your argument is that these ISPs have binding contracts with their customers to provide a certain amount of bandwidth. So if their customers use Vonage, then Vonage traffic should be able to absorb every bit of that bandwidth, all the time. It's hard to imagine that the amount of bandwidth they've promised customers is less than the 160 Kb/sec you claim that Vonage consumes. So if they can't handle all their customers simultaneously using 160 Kb/sec then they are guilty of fraud because they have sold something (bandwidth) that they are unable to provide.

    You are wrong, there is no tragedy of the commons here. Subscribers ARE *paying* for their bandwidth. They pay their ISP who of course pays their upstream providers. Nobody is uncompensated.

    You are also wrong that Vonage is complaining about smaller phone companies not providing enough IP bandwidth; what they are complaining about is ISP's *specifically targeting* and blocking VOIP traffic. Failing to deliver adequate capacity is another matter. There are no real quality of service guarantees in residential service, though no failure could be more grave for an ISP which, after all, has nothing to offer but bandwidth.

    Compression is not necessarily a good idea, not if it increases latency.

    Why don't they use encrypted packets and random or pseudo-random port numbers?

    That's pretty much the solution any time some idiot tries to filter your network traffic. At that point they either have to let it though or they have to start blocking any traffic they can't identify. And the latter option results in a substantially unusable internet connection and they'd lose all their customers.
