Hi Halomoan,
in OpenSER1.2.x, the flag concept is a bit more complex than in SER. For
nat purposes we use branch flags (per branch flags) and not general flags.
So, use setbflag() and istbflagset() to set and test. In location table,
see the cflags field and not the flags.
Also see that the nat_bflag is actually a param of "usrloc" module and
not registrar.
regards,
bogdan

Dear all
I followed tutorial from SER-Getting Start document for Mediaproxy to
solve nat problem.
I read on the Openser document
http://www.openser.org/docs/modules/1.2.x/usrloc.html#AEN83
<http://www.openser.org/docs/modules/1.2.x/usrloc.html#AEN83>
I have to use modparam("usrloc", "nat_bflag", 6) instead of
modparam("registrar", "nat_flag", 6)
And from the documentation, it said
"When SIP clients attempt to REGISTER with our SIP proxy we need a way
to tell the registrar module to
store NAT information for any particular UA. We do this by using flag
6, which has been arbitrarily chosen
(but defined earlier in the loadmodule parameter section). We could
have specified another integer here, but
flag 6 seems to be the accepted standard for nat_flag.
If the nat_flag is set before calling the save() function to store
contact information, SER will preserve the
NAT contact information as well as set the flags column in the MySQL
location table. By doing so, we can
call lookup(location) when processing messages and flag 6 will be set
for NATed clients."
I have a NAT UA is detected as NAT-ed UA by Openser with below rule
and do setflag(6); before it does save("location");
Why in mysql, location table, i see the flags column still 0 instead
of 6 ?
Did I miss something?
Please help :(
