In order to understand what unified communications as a service (UCaaS) is all about, it is important to first understand what it is not. The use of the term “unified communications as a Service” is somewhat confusing due to the fact that while there are some similarities, such as the fact that they both refer to the same product (your phone lines), they are not the same. A mobile phone has a hardware stack and a software stack. When you call your home phone, the hardware interacts with the operating system on your computer, which in turn interacts with the phone line. While this may seem rather straightforward, it is actually the underlying principles that underlie the communication process and what makes it what it is. Check Unified communications as a service.
The software on the other hand, is the one that interacts with the phone line and creates the actual message or audio or video that is delivered over the internet. If there were two different services, where one company provided the hardware and software and the other provided the message, this would be an example of a traditional service. This kind of scenario is also very common in the world of professional video and audio communication. The hardware and software are not the problem. The problem is making sure that both parties can collaborate with each other effectively and exchange information quickly.
With unified communications as a service (UCas), the actual communication takes place over the internet instead of through your local phone company’s network. You can use a smart phone, Blackberry, or any other number of wireless devices to make calls, send text and picture messages or even use email to communicate with the office. All of these functions are possible with an internet connection and the necessary software. The one thing that sets UCas apart from traditional communications is that all of this happens without ever having to connect to a phone line itself.
