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);

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, Daniel
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.
