As pointed out below the VoIP companies have, for cost reasons, let go
of the control of where a specific call terminates. That means that a
company lik Skype might not know where any specific call terminates,
or at least has no way of predicting where a call will terminate.
On top of that if you want to call using SkypeOut without being
traceable you just create a new Skype account, buy $10 worth of
SkypeOut minutes, use it and then discard it. That way you are
difficult to trace.
If you want to do computer to computer voice communcation you would
probably use a specialized program in place of Skype or Vonage if you
want to keep it secret (think Asterisk or Teamspeak) That way you
don't have to rely on any outside provider and the data will just be
data. I guess you could add encryption on top of that as well and
proxy it over port 80 and it would be impossible to differentiate from
people checking pictures on flickr.
I believe that all these measure only will affect the privacy of
normal people, and that it would have little effect on potential or
actual terrorists. They already have much more sofisticated ways of
communicating than speaking openly on unencrypted telephone services.
Just as wil a lot of the measures in airline securiy I believe that
this is a way of making it look as if they are doing something, rather
than actually doing something.
I think transparency, fairness, openness and information is a much
better way to fight terrorist tendencies than to create more controls.

Much VoIP termination is done by routing the call over IP to a
local termination provider in the LATA or even phone CO of the target
PSTN number. In many cases, these termination providers are
independent
entities. Larger VoIP companies have individual contracts with these
terminators, more rely on aggregators to have these contracts and
handle the settlements. Some VoIP companies manage their own
gateways
to the PSTN through a small number of chokepoints (this gives you more
control over the quality) but almost all of them rely on 3rd
parties and
aggregators to terminate the calls overseas. There are even bidding
markets.
