The uac module of Kamailio has support for doing remote registrations
for very long time (first added in v3.1.0, in 2010). There are plenty of
options to control if the registration done downstream differs in terms
of expire from the one received from downstream, when to enable/disable
these registrations, etc... The usual register/usrloc track the incoming
register requests, uac manage outgoing register requests. It might be
what you are looking for.
