yes, but contrary to SIP and h232, skype uses some p2p protocol,
that minimizes their server load (according to skype). thats no big
deal for the user, as long as he / she can still find an free sip / h323
service provider, but as bandwith does cost money, this might be a
another point of skype is that it can (does) "missuse" some skypers
that are not behind a NAT as some sort of server to connect two
NAT'ed skype users - that means: skype just works, without any

behind a NAT. this might be the reason 4 skype's popularity, and
there is no OS software i know of that has similar features.
