I use Rhub's on-premise web conferencing system which is a really good system actually as they take care of my web conferencing sessions as well as my remote support and remote access requirements. You just have to pay for it one time and then you own the appliance so it is quite a good bargain as there are no monthly fees or anything like that. You can check them out at Web Conferencing Appliance Remote Desktop Access Control Support PC Mac System Software Server Solution Meeting Conference Tool - hope this helps.
