I answer to myself (it may help others) as I could test successfully the
configuration below. Also there is a typo (isbflagset instead of isflagset):
so when I detect a UA is behind NAT, I do:
if (nat_uac_test("19")) {
if (method=="REGISTER") {
setbflag(7);
fix_nated_register();
...
Then when my B2BUA sends invite to this UA I do (after lookup("location") ):
lookup("location");
...
if (is_method("INVITE")) {
if (isbflagset(7)) {
setflag(5);
Regards,
Pascal

Is that correct ?
BTW, regarding the flag number, is there a table of reserved numbers ? Can
I use "7" in this case ?

Hi
A quick question, when I apply a fix_nated_register() to a remote user
when he/she registers, how can I know later on if this user is behind NAT ?
set a branch flag for REGISTER before save location. After lookup location
that flag is recovered and you can test it in the config file.
Cheers,

All my calls go through a B2BUA:
Caller ------> kamailio/rtpproxy ------> B2BUA ------> kamailio/rtpproxy
------> Callee
When my B2BUA calls a user, I want to know if this user is behind NAT or
not. For now all the calls go through rtpproxy but I would like to apply
this path only when user is behind NAT.

Pascal
