Asterisk is not a SIP proxy, we're a back-to-back-SIP-ua, b2bua.  
Everything ends in Asterisk and Asterisk,
being a PBX, decides what to do next.

In some cases we re-invite the media to go p2p, but SIP signalling  
ends in Asterisk.

In SIP terminology: We're a SIP registrar/location server, SIP  
outbound proxy (or can be configured as one to
be more correct) and a SIP b2bua, but not a SIP proxy.
