The 24 main UDP ports used for voice over IP will be blocked by ISPs in
Panama, the Panamanian government has decided.
The ports are: 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 move came in an apparent attempt to stem Cable & Wireless Panama revenue
losses caused by people using the Net to make international calls that would
otherwise have been listed on C&WP bills, says a November 3 LinuxandMain
It goes on, "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, published on October 25, the Panamanian government requires
'that within 5 days of publication, all ISPs will block the 24 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
"This 'unequivocally decrees that all routers, including those not carrying
traffic from Panama, but that might be traversing Panama, have the 24 UDP
The ports blocked include those used by software such as NetMeeting and
"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," it says. "There were
reports late Sunday that Panamanian ISPs were planning a demonstration aimed
at exhibiting their displeasure with the government action."
If other phone companies start to complain about the decline in revenue from
international calls as net-calls to any part of the world for the cost of an
Internet connection gradually take over, could something like this happen in
other countries too?
