A couple of weeks ago, I explored the migration to Unified Communications and gave my point of view about how the migration is somewhat determined by economics and the fact that enterprises have already set in place communications systems that have been paid for and work. But let’s say that you as an enterprise have determined the time is right to move to UC. Should it be premise-based or cloud-based? Some enterprises are worried about losing control and want on-premise equipment. But for many enterprises, UCaaS is the way to go as long as they are satisfied with the Quality of Service (QoS) and security. And by now, so many enterprises have moved to cloud-based UC that there are more than enough use cases and proof points that QoS and security issues have largely been overcome.
