Hello,
like Joel said, the reveiced filed in location record is set only for
NATed contacts and in ipv6 likely it is not the case.
What you should do is like:
$uac_req(ruri) = $(ulc (existingContact=>addr)[0]);
if($(ulc(existingContact=>received)[0]) != $null) {
$uac_req(duri) = $(ulc(existingContact=>received)[0]);
}
Cheers,
Daniel
