I don't know mate, something wrong with your config, all I can say from the provided info is that there's no place for *alias *in From/To headers. They must be in Contact/RURI.

I’ve tested with two different UA types and same thing happens, must be a result of the B2BUA sending the alias in the To header of the invite.

The alias is in the contact header for the invite sent by kamailio, so everything looks fine there.
Thanks,

Something wrong with the above From, no closing ">", also there's no place for *alias *in From headers.

Have an issue with BYE routing in a lab setup, any suggestions on what I should be looking at?
Topology:
UA1 <-> NAT device 1 <-> Proxy1 <-> Registrar/B2BUA <-> Proxy1 <-> NAT device 1 <-> UA2
All UA to UA calls flow through B2BUA.
All IP’s are public except for UA1 and UA2.
-Both endpoints can call each other.
-If the caller hangs up first, BYE is routed properly.
-If the callee hangs up first, BYE causes proxy to send 478.
On calls where BYE results in 478:
if(!isdsturiset()) {
……….…………………….not executed handle_ruri_alias()}
return;
Example issue call: UA2 to UA1, UA1 hang-up.
