Hi all,
I'm having an issue with ACK's being proxied. When an INVITE first comes in (new
transaction, new dialog), I do a 'www_challenge(...)'. This makes the proxy send a
'401 Unauthorized' reply. The client acknowledges this reply with "ACK".
This ACK is 'absorbed' by the proxy.
When during an established call/dialog the client sends an INVITE to set the call on hold,
this is an in dialog INVITE (with to-tag etc). Although authentication for this INVITE
isn't very necessary, my script does 'www_challenge' anyway. The proxy sends
'401 Unauthorized', the client responds with 'ACK'. This ACK however is
not 'absorbed' as it should be, but forwarded/proxied (or at least handed over to
the routing script). Is this intended behaviour? If so, how can I recognize this ACK to be
able to drop it?
I found some related info in this email thread:
http://lists.kamailio.org/pipermail/devel/2008-December/017246.html but doesn't
discuss this exact issue.
Though this isn't a big problem for me (the upstream gateway ignores the ack, and I
can disable authentication for re-invite's), I'm curious why the proxy behaves
this way. Hopefully someone can enlighten me.
regards,
Egbert.

do you create transaction before doing
authentication in second case?
ACK is absorbed transparently by sl module for stateless reply and they
get to config and absorbed by tm with t_relay() if it is an ACK for a
stateful reply.
So, even if it gets to config, does it get relayed? If yes, can you post
an ngrep trace of such case?
Cheers,
Daniel

98.123.118.16 = sip client, soft Phone [client]
77.14.12.129 = kamailio sip proxy [proxy]
63.78.36.101 = destination pbx [pbx]
Scenario:
[client] calls via the [proxy] an extention on the [pbx]. After being connected, the
[client] puts the call on hold by sending a re-invite. 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.

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

So, even if it
gets to config, does it get relayed? If yes, can you
post an ngrep trace of such case?
98.123.118.16 = sip client, soft Phone [client]
77.14.12.129 = kamailio sip proxy [proxy]
63.78.36.101 = destination pbx [pbx]
Scenario:
[client] calls via the [proxy] an extention on the [pbx]. After being connected, the
[client] puts the call on hold by sending a re-invite. 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.
