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.
How is accepting a call from an asterisk server different that one coming in on an analog line? Also, ideally, calls between VoIP systems should be via IP, rather than conversion to/from "POTS" service at each end.
The POTS system does not accept unauthentified calls. You, as user, may not know where the call comes from, but the telcos do. Plus, for a call going from a customer of one telco to a customer of another telco there has to be an explicit agreement between both telcos, on both technical and commercial sides. It is very complex. On the other hand, do you remember those movies where the bad guy makes a phone call to the police and the call has to last less than 20" or he is identified? That's rubbish, you are identified on on the first second, while ringing, at least on countries like Spain. Even if you tell your phone to hide your ID, you are identified if the recipient has the feature "do not accept hidden ID", which the police has, obviously. The problem nowdays is identifying calls from internet! From some gateways that allow the users to setup any calling number they desire without checking them. - -- Cheers / Saludos, Carlos E. R.
