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.
I thought that was considered a security risk.
Without direct and reverse DNS check, at least?
Yes, I expect Asterisk does that, but mostly for display reasons.
Maybe we're are mixing things up - I don't quite see the security risk in receiving a VoIP call from someone@some.where on the internet? The caller will not be registering on my Asterisk server, it's only an inbound call that is routed to whoever the caller wants. In my case, my phone on my desk (a Linksys SPA) is registered with the Asterisk server as extension #123, and calls to sip://per@jessen.ch are routed to that.
