There are numerous tools and clients such as SIPp (http://sipp.sourceforge.net/) and X-Lite (http://www.counterpath.com/xlite-overview.html); however I'm not sure which support qop. Keep in mind that some products are more lenient than others concerning non compliances.
A common qop problem relates to quotes. You can compare your headers to rfc2617 section 3.5 or post them to the list. You can verify that the UAC is generating the correct digest response by following the rfc2617 algorithm and using "http://gtools.org/tool/md5-hash-generator/";. A decent summary of rfc2617 is within "http://en.wikipedia.org/wiki/Digest_access_authentication";; however the rfc better reflects the quote removal. > -----Original Message----- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED] On > Behalf Of Stephen C.
