Harry,
Please do not email me directly. I will only respond to emails directed
to the mailing list.
To answer the questions you directed to me privately:
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.
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.
3) Music-on-hold works for us in the situations where it is needed.
Regards,
Norm

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,
onsip.org or iptel.org
#----------------------------------------------------------------------
# NAT Detection
#----------------------------------------------------------------------
if (!search("^Contact:[ ]*\*") && nat_uac_test("19")) {
setflag(FLAG_NAT_CALLER);
setflag(FLAG_NAT_PING);
fix_nated_register();
force_rport();
};
Regards,
Norm
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.
