Telstra has flicked the switch on its global cloud-based unified communications service, which will be available across four continents in 25 countries and delivered over Telstra’s worldwide network extending to more than 2,000 Points of Presence. The cloud collaboration service will be available from the end of August to customers on a monthly, “per worker” basis and would be delivered via Telstra’s cloud infrastructure, which now extends to seven locations throughout the United States, Europe and Asia-Pacific.
