Re: [Kamailio-Users] Registrar: Save modified contact / set the q value
Sorry for being unclear: I meant: Modify the contact in the script, then do
save().
E.g.
$(avp(contact)) = $ct;
# Those Patton can't send the q value ... Misuse their ;phone-context param
if (avp_subst($(avp(contact)),
/;phone-context=q([01]\.[0-9])(.*)?([^]*)/\2\3;q=\1/i)) {
# just to have it handy int that var(Q)
$var(Q) = $(avp(contact){s.select,1,}{param.value,q});
remove_hf(Contact);
append_hf(Contact: $(avp(contact));q=$var(Q)r\n);
# subst() does the same, also not save()ed
}
...
setbflag(1);
fix_nated_register();
save(contactimpl_nat, 0x02);

Is there any way to save(domain, 0x02) the contact after it has been

If it were not possible, how would nathelper:fix_nated_contact() work?

Yes, but if NAT flag is set, then RURI will contain the received ip:port in the domain portion upon lookup(), right? No, r-uri is the contact address from REGISTER. Otherwise, how do you get far-end NAT traversal for incoming calls (to the registrants) to work? dst_uri field is set to received ip:port, so the nat box is used as outbound proxy.

I guess I have been doing it wrong for a long time on 1.x by using fix_nated_contact() on REGISTER processing where NAT is detected, instead of fix_nated_register() and separation into contact and received as you describe. But in my case it works... -- Alex Balashov - Principal Evariste Systems LLC Tel: +1 678-954-0670 Direct : +1 678-954-0671 Web: http://www.evaristesys.com/ ___ Kamailio (OpenSER) - Users mailing list Users@lists.kamailio.org http://lists.kamailio.org/cgi-bin/mailman/listinfo/users http://lists.openser-project.org/cgi-bin/mailman/listinfo/users
Re: [Kamailio-Users] Registrar: Save modified contact / set the q value
If you need this in 1.5, try to fix the contact header and then forward the REGISTER back to yourself. The loopback REGISTER should have the fixed Contact header and now you can call save(). You will need to tweak a a little bit the config to get everything right into the usrloc (the loopback REGISTER will come from the server IP) and it might work.
