Hi Klaus!
Thanks for the hint! Indeed looking into the vsf=xxx parameter a little bit closer, I
found out, that on the reInvite the uac_replace() is done due to the Route: vsf=xxx Param
(knew that :-), but the vsf=xxx is not added again on to the Record-Route (missed that
:-). So the 2nd 200 OK doesn't contain it in the route-set anymore, thus the following
ACK doesn't have it in the Route Header.
Is it up to me to add it to Record-Route Header, if the Route Header contains these
parameters? Shouldn't the uac_replace() do that on replacing the From again?
Let's see, what I can do here.
Br
Walter

Hi Walter!
Automatic restoring uses record route parameters to store the original from URI. Maybe
there is something wrong with the RR header.
I can not remember any changes in UAC module, thus I am not sure if an update will help
you.

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!
