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. 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."

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.

Although realistically this is unlikely to be a problem for any significant percentage of Net traffic. Topologically, Panama is most probably a spur on the Internet, rather than a hub. Most of the western hemisphere's traffic passes through the US west coast on its way to anywhere. By the time a given packet hits Panama, I'd lay good odds its actually bound for an endpoint in Panama.

If the Panamanian government gets serious about this, they could put a stop to VoIP by making it illegal to use VoIP in Panama. Many countries have done this kind of thing in the past. In the UK 20 or so years ago, it was not possible to set up a public internet because of government rules.

Additionally, there is nothing preventing users from building a ppp, ssh, httptunnel or other tunnel over tcp and completely bypassing the UDP blocks from their workstation. It may even become a part of the software for DialPad or other platforms.

For phone calls, it doesn't matter if the data gets there two seconds after it was sent (ie. the reliable communication offered by TCP.) The data needs to get there now, or not at all. It's okay to have a quarter-second drop in a phone call.

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.

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.
Voice on Cable Modems (Score:4, Insightful)
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.
Moore's Law for Beer and Telecoms (Score:4, Interesting)
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.

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.

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.

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.

In Bermuda, a local ISP started offering VoIP back in 2000 on a DS3 provisioned into the US. Per minute charges via C&W: $1.10/minute. VoIP: $0.40/minute. Quality? A fuckload better on average than C&W. Now that the ISP has enabled SS7 for true 1+ dialing, the other traditional carriers have had to reduce prices.
Once the service was made available to the public, they were then threatened with termination of the DS3 by the submarine cable provider (not C&W, although they were in on trying to regulate out the use of VoIP except by the international carriers).
It was even worse when C&W mandated no other fiber systems could be brought into a country. They could set pricing on voice and data cicuits to milk the subscribers. Back in 96' a DS1 (T1) from Bermuda to NYC ran $85K... a month. Now it's down to a reasonable $17-22K/month (rack rate).
Sorry for the rant, but I had a bad week with C&W. Dropped a production frame circuit and when calling the Bermuda NOC I was told that it was a US problem and to call them (altough I contract and pay the Bermuda office).

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.
