BTW alternatively you can use dialplan the module to hold both regexp to
match and target IP with added benefit of in-database provisioning.

Hmm, the blind transfers should be transparent to the proxy. So the
REFER request should go all the way through box02 to box01 and to the
caller, which should send a new INVITE so the box01 can apply the same
logic of finding out where the subscriber is registered to RURI.

What is the actual call flow that you see after REFER?
