RE: [reSIProcate] CSeq not increasing.

["Derek MacDonald" <Derek@xxxxxxxx>]

That's fixed now.  Thanks Brian.

btw -- there are known issues with DUM retransmitting 200s.  I'll check that
fix in later today.

Subject: [reSIProcate] CSeq not increasing.


Hello,

I am just trying out your DUM project and really like what I see â?? in
terms of flexibility and ease-of-use. However, I have noticed a few
small issues , I have included a trace of one of my calls in this email.
To save you time sifting through it â?? the problem I am seeing is that
the C-Sequence number is NOT being incremented after authorization.
According to RFC3261 (Section 22.2)


When a UAC resubmits a request with its credentials after receiving a
401 (Unauthorized) or 407 (Proxy Authentication Required) response,
it MUST increment the CSeq header field value as it would normally
when sending an updated request.


The reason that the Cseq is not incremented is that the dispatch method in
the
DialogSet class does not increment it after it does authentication. I am not
sure where would be an appropriate place to increase the number â??
you could increase it the ClientAuthenticationManager handle method as well.

Any feedback would be useful,

Thanks,

Brian.
