[Kamailio-Users] UAC on ACK in reInvite

Hello All!

Tried to fix that anyhow but without success yet. Anyone who could just
tell me, if it's fixed in 1.4.something?

Scenario: 
A -> Openser 1.1.1 -> Openser 1.1.1 -> Openser 1.1.1 (UAC:normalize From
to phone number in national format) -> B

A Invites B	=> all OK
A reInvites B with T.38	-> INVITE => OK
                        <- 200 OK => OK
                        -> ACK    => From field not handled by UAC.

UAC config all default, so UAC restore mode "auto". Neither INVITE nor
ACK get's uac_replace'd in if(loose_route()) block, but INVITE get's
handled properly.

Upgrading to 1.4 or 1.3 is risky - or is it not? ;-) - because never
touch a running system, isn't it?
But then that customer comes with that Allied Telesis CPE :-) (And Ati
blames the proxy for not matching the ACK in the CPE although they use a
from-tag, too).

Many Thanks!

Walter
