Hello. I am starting a business which specialises in 'cutting costs' for already existing small to medium Australian businesses, focusing on their technology needs. We offer 3 key parts with 3 different plans. Our core 3rd party programs we use are; 1. Skype Business Console (http://www.skype.com/intl/en/business/welcomeback/) (http://support.skype.com/en). I suggest setup an account so you can access and learn how to add users, allocate credit, setup your restrictions on amounts users...
