[SR-Users] Absorbing ack's

Hello,
can you paste here the config actions used for handling the ACK?
I noticed some things for which I would like to see the config:
- the ACK for has Route header which is not consumed when ACK is relayed
- therefore looks like is not going through loose_route()
Load the debugger module and enable siptrace to see the actions executed
for the ack -- send the log here as well.
Another thing, sip requests that are relayed should be authenticated via
proxy_challenge()/proxy_authenticate().
Send also the output of 'kamailio -V' to know exactly the version you
are working with.
Cheers,
Daniel

The [proxy] does want to have that re-invite authenticated. The ACK send by the [client] acknowledging the 401 shouldn't hit the proxy routingscript, it should be absorbed by the proxy (I think). See the ACK CSeq 23146 in the sip transcript below.
