[Asterisk-Users] Newbie's doubt on sip.conf

In some diagrams, Asterisk take's the role of a SIP Proxy, but it is *not*
a SIP proxy by design. Asterisk answers SIP calls and originates calls as
just another SIP user agent client/server.

Asterisk is also acting as a SIP registrar, keeping track of where SIP
ua's are so we can place calls to them ([peer]s).
