Thanks Daniel.
I have a weird problem. As I mentioned in an earlier email, I have the following
dialog:
UA OpenSER SIP-Cloud
----INVITE---->
------INVITE----->
<---- 100 trying----
<---- 100 trying--
<---- 183 Progress-- (this one has sdp)
<----183 Progress--
(4 seconds later)
<-----606 Resource--
<----606 Res. -----
The called number is a PIC verification number that would announce the
long distance carreer. The goal here is to measure the time between
INVITE and 183 on the UA. But the UA sees this dialog as not established
and does not calculate the PDD.
I have been able to fool the UA by converting 183 to 200 on the OpenSER,
which makes the UA happy and it is showing the PDD correctly now:
UA OpenSER SIP-Cloud
----INVITE---->
------INVITE----->
<---- 100 trying----
<---- 100 trying--
<---- 183 Progress-- (this one has sdp)
<----200 OK ----
------ ACK-----> (I drop this ACK on OpenSER)
------BYE------>
-------BYE------>
<-----200 OK -----
<------200 OK----
This is perfect but what will follow is:
<----408 Req Timed out--
<---408 Req. Timed out--
The Cseq of the 408 shows that it's related to INVITE. Do you see what
is wrong with this setting and why I get 408 (which by the way sometimes
is 487 Request Canceled).
Thanks for the help.

OK, thanks, Nicolas. I just confirmed the ACKs
can be detected the
same way.
Now another question: is there anyway to generate an ACK locally as an
answer
to a BYE?
BYE does not require ACK, only INVITE.
Cheers,
Daniel
I checked the SL module but it only does reply and error but it
doesn't craft a
message.on its own like "ACK".

It should also work.
Have you check with tcpdump or wireshark that the ACK pass through your
OpenSER server ?
PS: May you keep the discussion on the mailing list...

OK, I'm able to see the BYE's.
How can I intercept the ACK's? I tried the same way but I don't see
them?
