I have my own OCS deployment including Live Meeting Server. I am able to schedule live meeting however I am supposed to use Live Meeting API to manage live meetings. So, I need to get 'conference center URL' to post my xml requests.
When I schedule meeting using standard LM UI and invite people then invitation link seems like this : meet:sip:erkaner@css.ceit.metu.edu.tr;gruu;opaque=app:conf:focus:id:80429381096943b88ca4816b2dba5ec9%3Fconf-key=l6r0rXnWJxNr
However, while I was using trial version of Live Meeting, invitation link was alike: https://www.livemeeting.com/cc/<conference_center>/<role>?<query-part>
And this url requires and shows Conference Center (cc). However the former one does not show conference center name.
