Is
this question coming from Panamian government? -:)

when you have to comply with some insane gov't ruling at penalty of
legal (possibly felony type actions) you will also squeal like the virtual
pig...
To comply with government, it is enough to SHOW blocking - block SIP and
H323 standar ports. It is not your concern, if SkyPE can make a tricks.

But I believe, that to comply with anything in Panama you need just to give
a $$$, not to set up acll lists.





This is internet - if I have 10 Mbit connection and 100msec latency, I
can
use it for Voice, no way to block me; if it is 19200bits/second and 2
second
latency, I can not. That's all. Other methods can provide temporary
reliefe
only.


true, this was the arguement put forth to the folks at the time, they
still insisted on their backwards, telco-minded thinking... Fortunately
after a few months they saw the light and removed the requirement.

Joe might not be that lucky, or he might be able to show precedent to
others about why it's bad to try to block the voip.

Perhaps 'I am failing to see it' but, what can be gained by blocking
VoIP
traffic other than freeing bandwidth and CPU churnings?

reference panamanian gov'ts choice to protect legacy/incumbant carrier
business by blocking voip. no one said it was 'smart' just that it was
what the gov't wanted. Perhaps Joe lives in a similar situation?
