The term VaaS started to become relevant in the last two or three years and it is widely considered to be the natural replacement for the current time-division multiplexing technology. In short, VaaS allows companies to offer telephony services that are high quality, reliable and cost effective, over the internet.
The late rice of VaaS in relevance can be directly attributed to the advancement of high speed internet that, in turn, has allowed for more reliable and stable connections, the development of more sophisticated VoIP applications and for far easier integration with more robust solutions including those that allow you to incorporate other features such as instant messaging, screen sharing, video conferencing and presence management.
Voice-as-a-Service is becoming more and more prevalent in call center environments where the quality and stability of a call is paramount to ensuring customer satisfaction. When you add in the cost effective benefits of utilizing a VoIP application, decision makers do not have to think long or hard before jumping on the VaaS bandwagon.
The bottom line is that the days of accepting low quality web-based telephone calls are gone. Technology has finally caught up with the technical requirements of enterprises looking for solutions that can help their organizations provide better communication internally and with their customers.
