I suspect you could have the typical problem of "Contact" double overrided (by
In your scenario OpenSIPS retrite Contact header coming form U1 in case NAT is
detected (so in-dialog requests from the remote could arrive to U1).
For this to work, Contact must NOT be also rewritten by P2. A bad
configuration could force P2 to rewrite it.
I would check that first (check if Kamailio P2 is rewritting the Contact
header of U1's INVITE).
