Who forwards Registrations to Asterisk or PBX, and who lets Kamailio maintain Registrations?
That all depends on what you're trying to accomplish.
But one historical problem with Asterisk has been that Dial()ing peers through a trunk sip.conf peer to reach them via a centralised registrar broke certain Class 5 features (MWI, presence stuff) that relied on contact bindings being in local AstDB.
As I understand it, the new chan_pjsip driver has effectively vanquished that problem, so it makes no difference if your registrar is outboard or internal.
