Panama Decrees Block To Kill VoIP Service
An anonymous reader writes "In an apparent attempt to stem telephone company revenue losses due to Internet telephony, the government of Panama has decreed that 46 UDP ports be blocked by all Internet service providers.

How difficult could it be to write some software to use VoIP on port 80 or some other commonly used port?
Banning VoIP? Whats next? Possibly banning email to help the USPS?
And why did you staple the trout to the RAM?
There are 65534 other ports wich can be used for VoIP, they must block them too!
Please adapt.
People have tried to fight progressive technological evolution for ages and it has yet to ever work once. Any country making laws forcing its citizens to live behind the times is only hurting itself. What if panama had outlawed the original telephone because it hurt the post office? Granted, Voice IP isn't quite as drastic a step, but it is progress and it will succeed on its own merit, laws or no laws.

If person2person chat programs with voice capabilities, then whoever provides the software (I know Yahoo messenger and ICQ can do that, although it's not VoIP) should be able to make it switch ports easily.
If companies (such as the one I use to call Russia if/when I ever do
Or is my logic flawed somewhere and the port block like that would achieve the desired effect?

The obvious solution is going to be a transmission tax on VoIP calls. Cheaper than the old way, but it will begin to cost you money. Hate them you might, but the phone companies have real expenses in physical property, technical services, and customer service. They need to get paid. It will be less than they are used to, but they won't be giving it away for free much longer.

In fact, I think it would be a piece of cake to cobble together a proxy server that did just that. The clients wouldn't even have to change their software other than to point to the intermediate proxy server.
The problem here though comes in talking to the rest of the world. The above-mentioned servers have to direct the traffic to the destination servers at some point. Those servers are completely outside the control of the subversives to be. Those servers have to know that the traffic being received is actually VoIP and deal with it appropriately.
It can be done, but it will require servers outside of Panama to cooperate with the scheme.
Of course, once the Panama government locates those sites (shouldn't be hard) they'll start gopher whacking them with a variety of tactics: legal shutdowns through warrants, DOS attacks, etc. Vendors from outside of Panama will also rush to fill the void, and that software will also subsequently be outlawed.
The bottom line though is that the government will not be able to control the VoIP "problem" entirely without just pulling the plug on all Internet activity. That would be a steep price and they will face economic pressure to not do it.
Oh well, they'll learn this one the hard way I guess.

I would assume that there will soon be:

VOHTTPOIP
VOICMP
Example: I buy a new tool. It is a clawhammer. For some reason, this deprives the company making nail removers of money, especially considering their old nail removers were overpriced.
So, the government affiliated nail remover maker goes and makes buying clawhammers illegal.
This is immoral. You can't just rent-a-law because your overpriced technology is being smashed by a preferrable alternative.
I mean, just because you can buy laws (ie: riaa), doesn't mean it should be allowed to happen..
What this article really demonstrates - and it's something that has been demonstrated before on countless occasions - and that is that most governments of the world believe the internet is something tangible and easilly controllable.
This has been demonstrated here in Australia with the federal goverments push to sensor content and make ISP's liable for content that is served up from their service.
It's been demonstrated by the Chineese government with their sensorship and blocking of sites like google.
It has been shown by the USA's government in their restriction of encryption technology export.
All of these things are easilly worked around by even the most non techsavvy user.
Those of us who understand what the internet is and how it works understand that this sort of filtering will not work. These type sof things just show that until governments actually gain an understanding of the things they are trying to control they will continue to make fools of themselves. (btw: I'm surprised they dont want to block tcp ports 25, 110 & 143 (smtp,pop,imap) as people might send electronic mail rather than using the snail mail service).
the U.S., as well as many other countries, already do, albeit in a different industry. When the U.S. says: "You, as a citizen, are not allowed to circumvent insuring your automobile, say by having infinity cash [sic] that you're willing to use to pay for any damages that you might inflict, but must go through a PRIVATE, government regulated insurance agency in order to use the public roads..."
Except for satellite and other wireless communications, ALL VoIP in Panama (as elsewhere) goes through wires that sit on the Government's land (that would be everything). If I can't use a public road except by playing by the rules of regulated private companies, (even if I know of a cheaper alternative), why should Panamians be allowed to use data lines going through public land, except by playing by the rules of a regulated private company?
Okay, that's the most contrived example I could think of. I don't think there's a closer equivalent -- some candidates were Edison (the electric company) - run public schools (look it up -- but you're not required to go to one, since you can homeschool) and private appraisals mandated in certain cases by the government.
Anyway, uh, yeah, HOW DARE THEY.
On the positive side, this should kill the Windows Messenger popup spams, which propagate over UDP ports.
On the negative side, it will kill Quicktime, which needs UDP ports for negotiating a connection.
In an apparent attempt to stem telephone company revenue losses due to Internet telephony, the government of Panama has decreed that 46 UDP ports be blocked by all Internet service providers.
The ports include ones that are commonly used for voice over IP as well as some that are used for other purposes, apparently with the idea that these, too, could be used to circumvent the POTS (plain old telephone system, a term of art) in making telephone calls.
In the decree, the Panamanian government requires "that within 5 days of publication, all ISPs will block the 46 UDP ports used for VoIP and any other that could be used in the future (which could end up being all UDP ports)," according to a reporter and computer consultant there, and that "the ISPs will block in their firewall or main router and in all their Border routers that connect with other autonomous systems."
This "unequivocally decrees that all routers, including those not carrying traffic from Panama, but that might be traversing Panama, have the 46 UDP ports blocked."
The significance of the government action affects areas far beyond that nation. Due to its geographical location, numerous undersea cables connect in the country, making it a substantial hub for international IP traffic.
Among the services that are to be disrupted are NetMeeting, Dialpad, and Net2phone, which labels itself "communication without borders," a claim which apparently will no longer be true if one of those borders is Panamanian or communication is between two countries whose IP traffic passes through Panama.
The decree is apparently rooted in complaints by Cable & Wireless Panama (Motto: "If you're worried about your data, voice, or Internet service provider, we're here to help"), which says it is losing money due to users employing the Internet to make otherwise expensive internetional telephone calls -- calls that would otherwise be listed on Cable & Wireless bills.
The UDP ports involved include: 1034, 1035, 2090, 2091, 5000, 6801, 6802, 6803, 9900, 9901, 12080, 12120, 12122, 22555, 26133, 30582, 35061, 38000, 38100, 38200, 47563, 48310, 51200, and 51201.
The decree was published October 25.
Among the services that employ some of those ports are "nlockmgr," the NFS lock manager responsible for rpc.statd and rpc.lockd, which in turn are responsible for crash recovery functions for locked files and for processing file locking requests, respectively; telnet; and numerous VoIP services.
In addition to those who wish to save on their phone bills, the government order blocks the perfectly lawful use of those ports by businesses that have legitimate VoIP applications allowed in the country.
There were reports late Sunday that Panamanian ISPs were planning a demonstration aimed at exhibiting their displeasure with the government action.
Out of simple curiosity, I plugged 'panama phone company' into Google.. after all, what could this little pissant country have in the way of phone companines? And what are the first two links to pop up?

ps.. I'm sure Panamanians by and large dislike this as well.. the 'pissant' is directed at the governmental representation of Panama, which right now looks suspiciously like a boil on someone's ass.

In the long run, violent overthrow of the government worked OK for the French, English, and the United States. It's more of a last resort, though.
Adapt or die. There is no rule that states established businesses get to do business "the old" forever. If a better cheaper way of doing things comes along, oh well, tough cookies. There were once a lot of blacksmiths as well. So to the phone companies I say, Adapt or Die, better yet just die.
If you wanna get rich, you know that payback is a bitch
Actually, you're wrong. If you have enough cash and can prove it (by posting a bond for example), in many states you can avoid purchasing insurance. Essentially, you are self-insuring yourself. Whether that is a smart thing to do is another question entirely.

People have been saying for years we need transparent encryption of internet connections (OK mabee I've been saying it) Once 'important' countries like Panama start playing routing games like this it becomes even more important.
Such heavy handed actions might be just what projects like FreeSwan need to get more universal acceptance. That all being said does anyone honestly belive that panama will be able to block *all* UDP traffic, while they are at it is might be a good idea to block ICMP and TCP - both of which could potentially carry voice data as well.
There is no money to be made in telecommunication in the long run if technology runs its course. Or at least it is going to gross millions instead of billions. In that situation even the remnants of the industry remaining today would largely have to collapse.
... with Bush's soft stance on monopolies the time is ripe to bring the US a couple of steps closer to corporatism, and after that the WTO and globalization can take it on a world tour, and the combined bribing power of the content and the telecommunication industry might just be the force which can accomplish it.
The industry is too big and too rich to go down without a fight, in Panama this results in naively blatant intervention. In the US the telecom industry will probably pair up with the content industry to outlaw private private peer to peer broadband communication sooner or later, under the guise of security and copyright protection. Only a monopoly or a price fixed ogliopoly will be able to squeeze money out of people on the same scale as today for communications in the future
This is very embarassing, but not a surprise.
This is yet another example of our British friends at Cable & Wireless adapting to the local culture of the country which they're sucking the blood out of. They obviously have quickly learned the Panamenian way of politics and have paid off all the necessary politicians, which can often be bought very cheap.
Cable & Wireless is privatization gone totally wrong. The previous phone company was a government owned company called INTEL, and Cable & Wireless beat US GTE and took over the phone system of Panama. The results have been horrible.
Local calls in Panama used to be like in the US, you paid your minimal fee and could talk all the minutes you wanted. Cable & Wireless brought the wonderful European model of paying for each minute for local calls.
If that wasn't enough, they also charge you per minute (I think) for calls from a land line phone in your house to a cell phone. That is, you pay for calling a cell phone and the person on the cell phone pays too. I had to find this the hard way after making a few calls to some friends from my grandmothers house.
So, people are fed up with them, and the internet savy are using Voice over IP a lot. I used to receive a lot of calls from a cousing over dialpad.com (when it was free). This was the ideal system to make a call to the US, dialpad was for US calls only, but the funny thing is that this worked great if you lived in another country.
Here's a good article on the whole mess Cable & Wireless is creating;
A Case of Privatization Gone Wrong -
Panama's Wires Crossed
- sigs are for wimps.
...the more they stay the same. The third-world telco monopolies have been fighting a similar battle against long distance "callback" companies for over five years now, and for the most part they've been losing badly. They've known for a while that VoIP services were the next big threat, but it doesn't look like they have any better idea how to deal with them.
One detail that usually gets left out of these articles, though: the "local third world telco monopoly" is not in any way a homegrown Panamanian entity. No, the citizens of Panama, like most of their neighbors in the carribean, are getting royally screwed by our dear friends at Cable and Wireless.
News for Nerds. Stuff that Matters? Like hell.
The government of the United States passed a new law prohibiting the manufacturing of internal combustion engines in order to protect the extensive investments of the horse-and-buggy industry against the encroachment of "automobiles". A new 50% tax increase is also planned on the steel and rubber industries as the products of these industries are used extensively in the manufacturing of "automobiles"
...that's the same Cable and Wireless, aka Exodus, where Slashdot currently hosts all of its servers.
News for Nerds. Stuff that Matters? Like hell.
As funny as you thought that was, it's painfully close to the truth. The U.S. government recently enacted a 38% duty on all soft-wood lumber imports from Canada in order to protect its own lumber industry. Now they expect Canada to supply raw logs for processing south of the border (not to mention cheap electricity with which to process it).
I lived in the country in the Mid-90s (after Manuel).
And it once again sounds like the corrupt workings of their ruling junta.
Typical situations:
Transito (traffic cops) targetting rich foreigners for some BS violation, so they could receive bribe money. It was so common, that my friends always planned on taking extra cash to pay corrupt traffic cops.
The railroad system turned over by the US (at the time already "turned over" to the Panamanian govt) which in a few years had became totally non-operational due to local inept management.
Many reliable stories of gov't for hire (much like the US) where the politicos where bought off, not by campaign contributions, but people bought by large amounts of cash for personal gain.
All in all the ordinary people of Panama were friendly and had the attitude: oh well it happens, might as well be happy. (Papas e chulatas) Potatoes and bacon. oh well.
Personally I am surprised the Canal still operates. But one thing most Americans don't realize is that a provision in the treaty stipulates the US can reclaim it if it becomes non-operational. That in my opinion, is the reason the canal hasn't followed the fate of everything else "turned over" and ruined by its corrupt govt.
--side issue here. You CAN do an indemnity personal bond for car insurance, just most people don't and it's little known about. It's also expensive, goes by state minimum liabilites, and you'd of course want more than those minimums any more with the cost of cars and people in the hospital, etc, but if you got it you can do it and keep your wealth unless it's needed by your proven negligence.
Got a neighbor periodically goes to panama for his oil business stuff, he sez the government there is roughly equivalent to say chicago in corruption levels, ie, total top to bottom. I imagine them mucking with the internet only applies to peons, that if you are at least a semi connected fatcat and pay the correct bribes you can do whatever you want, but at that level you could afford long distance so the point is moot. Most (not al, generally speaking here of course) civil laws in regards to anything but fraud in it's various forms more or less exist to protect the already wealthy's status quo. No different here than in panama, not really.
I'll give you an example I am running into locally here where I live. I'm in the market for a small piece of property to have a home on. My income level for this would be in the uber cheap range. Anywho, this county a few years ago decided on a minimun acreage size for new homes, 1.5 acres. Well, ok, fine and dandy..... trouble is, for the decades preceding this, they "allowed" smaller than that to be deeded up as lots and now exist in undeveloped abundance by the hundreds or thousands really, like 1.1 acre, etc. These lots are now useless except for growing weeds and trees, people are stuck with them now, no one wants to buy them, you can't do anything with them, but they are still taxed. This benefits the more recent richer arrivals who took the county over(lotta cash under the table money gets spread into country government is the popular notion) and don't want it to be farming/light manufacturing, they want it to be yet another yuppie retirement/second home vacation place.
Poorer people are untermenschen here, you can WORK here, but they would rather you to live over real far away some other place and commute, please go home at quitting time, no riff raff. It sucks but that's another example of a civil statute enforced by their bureaucrats and hired badged mercenaries to benefit the more wealthy.
It's not perfect - Compressed RTP does a CSLIP-like elimination of most of the IP, UDP, and rTP overhead, but doesn't work over IPSEC or most other tunneling protocols.) That means bandwidth is pretty tight over 28.8-upstream dialup modems (especially if you don't always get full speed), but I'm not aware of any better tunneling solutions.
It'd be nice to have some tradeoffs like putting more than one voice sample per IP packet, which is not so hot for quality but cuts the packet overhead in half, and the protocols *ought* to have encryption as a standard feature, so you don't need tunneling for the general case, but it's a good start.

You are incorrect. There is no port number in an IP header. TCP and UDP both have their source and destination ports as the first 4 bytes after the IP header, but ICMP, for example, does not have ports at all. Thus, the concept of a port is defined by the upper layer protocol and has no meaning at the IP level.
A decade or so ago, when Joe Nacchio was working for AT&T before he started Qwest, he gave us a talk at Bell Labs where he drew a curve on the screen that showed the market price of long-distance voice telephone minutes. It took a steep dive, settling down asymptotically toward zero; given the prices of the time, he was showing it going from a quarter to a dime to a nickel to a penny. What could we do about it? Well, the choices were adapt or die. Use technology to cut costs, and use lower prices (plus advertising) to get people to make more phone calls.
Many countries' PTTs were abusing their monopoly positions by charging excessively non-cost-based prices for their service, ripping off their customers and damaging their overall economies by interfering with international communications and therefore international trade. In the past couple of years, they've been taken down not only by callback companies, but by wholesalers using VOIP technology to keep their costs much lower than the PTTs costs. Everybody wins from that, except the greedier PTTs, and most of them were using excess international prices to cross-subsidize local calling.
What's the next step? What happens if VOIP drops costs to the equivalent of $0.001 per minute? The most likely big impact turns out not to be the costs, but the fact that you no longer need a gigantic expensive #4ESS telephone switch to route large numbers of calls - internet routing technology works quite well for that, with something DNS-like to help with end-user location. Unlike those of you who aren't in the telephony business, yes, we do care that our last several business models have gotten the chairs kicked out from under them, but the problem of proposing new business models for telcos is ours, not that of the people who are trying to make us obsolete.

Two of the problems of VOIP over cable are service reliability and reliability during power failures. The easiest way to fix the latter is to integrate some cheap cellphones into the equipment. Service reliability's a bit harder - the economics of the cable TV business assume that you need enough technicians and trucks to take care of most failures, so customers are happy and you don't need to rebate their bills for downtime very often, but that fundamentally it's just television, and if it goes down for the weekend in bad weather, your customers can read a book or go watch videotapes until you can get it fixed.

Then how do you suggest people that live in small towns get to work and shop if they do not have a personal automobile/roads? Mass transist does not work in a small town.
I don't know whether you have lived in a small town. I have, in Europe. It took three minutes to walk to the supermarket, five minutes to walk to work, and three minutes to walk to the train station (which would take me directly to the airport and pretty much anywhere else). For short distance trips, I'd use a bicycle or the bus (fast and on-time).
The quality of life there was unmatched by anything I have found in the Bay Area (where I live now), even though I made a fraction then of what I make now. The sad thing is that most Americans don't realize how poor the quality of life in America actually is. (In case you are wondering why I didn't stay there--it's because my friends, family, and job are here.)
And some of those 'corrupt' politicians dismantled public transportation because it was/is a very large sinkhole for tax dollars.
Cars are a much bigger "sinkhole" for tax dollars than public transportation. Even disregarding all the infrastructure costs, health costs and lost productivity from cars alone are enormous and dwarf anything spent on public transportation.
They want to block UDP ports that *can* be used for VOIP? Why not *make* 'em block all UDP and let them find out how screwed that actually leaves them? Wanna see a government backtrack on a previous decision really quick?
Unless Panama wants to block all web browsing...
Bear with me while I explain
UDP is used for VOIP because TCP is a streaming protocol and as such isn't particularly useful for real-time data transmission -- as said by another poster elsewhere, it's preferable to just simply lose a packet every now and then rather than to have the connection pause suddenly while TCP handles congestion control.
So... what I imagine is this: a system running VOIP listens to a randomly chosen UDP port rather than a specifically chosen one. The exact port to try to connect to is found by connecting to the system via the TCP port 80, and the VOIP system responds to the connection request letting the caller know which UDP port to actually use, and then the TCP connection is closed. The caller can then use the UDP port it was informed about. Since the system can be listening on ANY UDP port, possibly even one that would normally be used for some other well-known service, the government would have no choice but to create a ruling that would unilaterally block all UDP.
Seriously... I think it would be close to hilarious to see what they would come up with to try to stop that.
File under 'M' for 'Manic ranting'
Panama is, unfortunately, not the only country to try this. Pakistan, for example, has one telco company handling all outgoing internet traffic (telco monopoly until dec 31 2002). They blocked various VoIP sites *and* MSN voice chat last month.
This was done unilaterally, with support from the supposedly independent telco regulation authority.
People complained, ISPs took out ads in papers and made press releases about it, and it's now looking like the sites will be unblocked by the end of the week. Hopefully.
Although John Dvorak was speaking about copyright law when he said this, It still sounds appropriate:
What's happened, and the point I keep trying to make, is that technology has changed the economics of these industries.
This is indeed true of teh VOIP scene. What a pathetic lack of understanding of the technology the Panamanian governement has displayed. Many of those ports are just as easily used by many apps that they definately don't want to ban. Exchange Sever is one example, but there are many more.
