Hello list.
I know that probably this questions is more related to the SIP protocol,
but is causing me problems and this is a very supportive list.
I'm using a HT-286 from Grandstream behind NAT.
This is the REGISTER sequence :
U 200.120.46.99:29786 -> 200.100.154.35:5060
REGISTER sip:myproxy.mydomain.net SIP/2.0.

As you can see the initial REGISTER has a Contact header like this :
Contact: *.
Is this ok?. Is this ok by RFC?
What does this means?
In my cfg file I have :
route[2] {
#
-----------------------------------------------------------------
# REGISTER Message Handler
#
-----------------------------------------------------------------
sl_send_reply("100", "Trying");
if (!search("^Contact:\ +\*") && client_nat_test("7"))
{
setflag(6);
fix_nated_register();
force_rport();
};
So I think is not matching the regexp "(!search("^Contact:\ +\*")"
therefore is not fixing the contact.
Any ideas?
