To overcome what Alex described, PATH module provides a simple but powerful
solution to be used in intermediary proxies. In such a scenario, Kamailio
only forwards Registrations.

For the other option, have a look at the famous example:

About use of PJSIP, I've had my part of disappointments and inconsistencies
when it comes to integration with an edge proxy, hope others have more luck.

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.
