Ani,
It's not clear from the article above but "conf:sip:anirudd@vdomain.com;gruu;opaque=app:conf:focus:id:ABCDEFGH%3f" is a comman line parameter.
So this should read....
.......you can open windows run prompt and type the following:
communicator.exe conf:sip:anirudd@vdomain.com;gruu;opaque=app:conf:focus:id:ABCDEFGH%3f.......
This cought me out and thought I'd share it.
Great article, helpd me a lot in diagnosing a LYNC issue we have had here,
Thanks, Brian
