Hi Andreas,
yes, that is true - is a bit of complicated to calculate the response
when qop is on. Have you tried the approach suggested by Thomas? to
completely ignore the qop from challenge and to send the response as if
no qop was received......

I've make some tests to deeper understand qop, for this I've modify
the auth_hdr.c to
ignore the qop and add a static qop=auth to the outgoing authorization
header, but this
way wasn't successful.
After review of RFC 2617 I found that in case of qop cnonce and
nonce-count (nc) MUST
send by the client so it's not so easy as expected.

Hi Bogdan,
I think for the qop it could solved very quickly if only the auth
method will be implemented first,
because the Digest for auth should be the same as without qop
(unspecified) see page 14
in the following example....
http://www.softarmor.com/wgdb/docs/draft-smith-sip-auth-examples-00.txt
so it should work as follow....
if qop is detected, parse qop value if "auth" is allowed, if yes send
Authenticated Request as without qop,
but add qop="auth" or qop=auth ?! ........if *only* auth-int is
allowed goto error as before ;-(
This should make a lot of users happy......
Am I right? Is it possible for somebody to do this soon ;-)

Andreas

Hi Klaus, Hi Stefano,
fixes to these limitations are scheduled to be done, but I'm afraid
they will not be ready for the next release - more time consuming
things are on the roll and I personally prefer to finish them before
attacking something new...
Regards,
Bogdan

Hi,
i would like to ask if the two known limitations of
UAC Module
(authentication does not support qop; CSeq not increased during
authentication) will be resolved in future releases and if
anyone has developed a patch or is working on it.
I wonder if the dialog module can be used to keep track of the
CSeq
difference between the SIPclient-->openser and
openser--->upstreamSIPcomponent and modify all messages on the fly?
Or another idea - would i be possible to store the Cseq difference
in the record route parameter of uac module too?
regards
klaus
