What protection do you have against wiretaps in North America whether they are
done legally
or not?
How do you know that your call originating and terminating in North America is
not being
routed/switched via another country where there is no legal protection against
wiretaps?
Do you naively believe that security agencies and goverment employees in any
country
always adhere to legal requirements?
And how would you even know if your telephone call on the PSTN side of the VOIP
-> PSTN
call had been intercepted?
If you want to keep your conversation secret, you should not be using the
public telephone
network no matter in which country you are making the call.
All an encrypted call to a VOIP->PSTN gateway will assure you with is that
nobody in
the Internet chain between you and the VOIP company can listen in, unless of
course they
have already cracked the encryption method.
