1) Perhaps if you post your complete .cfg file,
someone on the list
will be able to assist you. There is a very good
discussion of NAT
registrations at the onsip.org web site. Are you
100% positive that
your code snippet is being executed during a
REGISTER message ? You
might want to put some xlog() statements in your
configuration file to
make sure that the fix_nated_register() is being
executed correctly.
I post my ser.cfg
2) I use a flag called FLAG_NAT_CALLER so that the
rest of the
configuration file can test the flag to determine if
the CALLER is
behind a NAT and take appropriate actions if that is
the case. In the
code snippet you sent to me, you are using
setflag(7). I have no idea
what this is, but I'll bet that it serves a similar
purpose to my
FLAG_NAT_CALLER.
# -- registrar params --
modparam("registrar", "nat_flag", 7)
modparam("registrar", "use_domain", 1)
I don't understand how this flag could help to rewrite
th sip contact header.
3) Music-on-hold works for us in the situations
where it is needed.
Can you explain me ?
SER is not a PBX what about IVR ACD VOICEMAIL and more
that's why I whish using asterisk for telephony
features and SER as sip router .

Perhaps you are using fix_nat_contact() when you
should be using
fix_nat_register().
Note that fix_nat_register() should ONLY be called
when a REGISTER
method has been received.
The example below uses a couple of M4 defines, but
otherwise might
work for you. If you have any questions about
the
statements below,
please review the documentation available online
at openser.org,
# NAT
Detection
if
(!search("^Contact:[ ]*\*") &&
nat_uac_test("19")) {
setflag(FLAG_NAT_CALLER);
setflag(FLAG_NAT_PING);
fix_nated_register();
force_rport();
};

p.s. In regard to your previous problems with
devices registered to
Asterisk, I found that it is a much better idea
to
have all of the SIP
devices register with (Open)SER instead of
Asterisk. This solution
may not be right for you, but it's the way we
prefer to do things.
