<div>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

module(also i need to cover all ipv6 info since i am
proxying from ipv4 to ipv6).</div>
<div><br>

<div>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.</div>
