Multisite is for TelePresence endpoints only, it's used so they can host small 4 participant conferences themselves without the need of a larger conferencing bridge such as a TelePresence Server. I see from your other post, vts-cucm, that you have CUCM and a virtual TelePresence Server, as mentioned in my reply there, you'll be required to use Conductor with the virtual TelePresence Server. You'll need to license the vTS with either screen licenses or personal/shared multiparty license in order to host conferences on it, if you don't have either of these, your Account Manager can help tell you what you need and get you in contact with a reseller so they can be purchased. If you'd rather not purchase them, he can provide timed demo licenses.
