Yes, but connected to the internet, and known to other servers outside. Not trivial.
To make calls on the internet, the asterisk server does need an internet connection, but it doesn't need to be known to other servers. It is actually fairly trivial :-)
Making calls to somebody else registered on another server? Normally any sane asterisk will refuse an incoming call from another asterisk that is unknown.
No it won't - it would never receive any external calls if it did. Any SIP-client can call me at sip://per@jessen.ch without my asterisk server knowing about where it comes from other than it's IP-address.
afaicr, that is configurable in asterisk. You can set that * will refuse incoming call's from hosts that did not register before. Normally voip soft/hardphones should register on your asterisk, and your asterisk should register at your VOIP-provider. You don't have to do that, but it's a security issue.
