Thank you Daniel. It will work if i have username and password in db or
something else.
In this case i am getting the register from the sip client and i dont have
the passwd but i need to forward it somehow via uac and on challenge pass
it back to the sip client.
I have done this with $du and works but when an invite comes from the b
side(sbc) to the a side(thesip client) there is no aor or anything i can
lookup to pass it along. Which is what i am trying to resolve.
The sbc do not support path and ob header correctly. And cries when it gets
any ipv6 address.

can someone please guide me where to find the usage of auc module, thanks
in advance.
I am registering the uac in one end then i want to forward that
registration to an external registrar, if i use $du some domain, some of
the ipv6 info is going to be forwarded, i need to make it look more like an
a b2bua than a outbound proxy therefore i need to use the auc module(also i
need to cover all ipv6 info since i am proxying from ipv4 to ipv6).
i am able to register the client to kamailio, then kamailio send the
registration to the external registrar, but when the registrar sends back
the challenge uac does not reply, any ideas how can achieve this.
uac(linphone etc) --registration--->kamailio(registrar
module)------register(uac)--->SBC
sbc----invite---->kamailio(lookup)---------invite---->uac(linphone etc)
this is the code i am using.
# Handle SIP registrations
route[REGISTRAR] {
xlog("REGISTERING ");
if (is_method("REGISTER"))
{
if(isflagset(FLT_NATS))
{
setbflag(FLB_NATB);
# uncomment next line to do SIP NAT pinging
## setbflag(FLB_NATSIPPING);
}
if(af==INET6)
setbflag(FLB_IPV6);
xlog("IT IS IPV6");
if (!save("location"))
sl_reply_error();
route(REGSBCFWD);
exit;
}
}
route[REGSBCFWD]{
xlog("CREATING OTHER LEG TO THE SBC");
if(!is_method("REGISTER"))
{
return;
}
