Someone like Magrathea will do VOIP-PSTN termination.

The main point with VOIP is most of the long distance transit happens
on the internet. On the traditional PSTN you have to pay per km the
call travels, while on the internet the transmission is 'free'. So
what usually happens is the call travels over the internet to somewhere
near to the recipient, and then it is transferred over the PSTN for the
minimal distance.

Effectively all calls become local or national ones inside the
destination country. So you can call the world for the price of a
local call (in the destination country - these prices vary quite a bit
from country to country).

Since it's VOIP, it doesn't have to be local to the destination either.
If it turns out to be cheaper to call UK mobiles from Nigeria than it
is from the UK (such pricing anomalies happen regularly) then VOIP can
send the call to Nigeria to enter the PSTN there.

I guess you can do the same even without having voip yourself, you can
dial a`local gateway/access number, where you can choose a network code
(peer code) and dial also the number of that user. www.sipbroker.com can
help you with that. aka calling card ? (like Callcentric)



Does it mean that they VoIP provider have a local connection in each
country ??????
Or they probably hire this kind of equipment ??

That's I would like to understand, how `physically` the phone call will
arrive in a different country (On a landline for instance )
