Deploying VoIP in a business not only allows to considerably cut down communication costs, but also adds more power to the communication process and infrastructure. For instance, new VoIP systems have PBX functionality and tons of other features and are very flexible and scalable. They also are geared towards Unified Communications, converging into one device voice, text and video, and enhancing presence management.
Deployment has been something of a headache for administrators lately, the main challenge being the initial cost and setting up. So it has been much question of return on investment, and subsequently the question of 'worthiness' of a VoIP deployment. For this reason, only big companies considered such a move. But now, the new systems are becoming quite compact and integrated. You can find all the functionalities of a whole communication system into one single device, and setting up is only more than a breeze. Adtran Netvanta is an example. Here are the most popular business VoIP solutions.
For smaller businesses, there are still smaller systems, much like home phone packages, but tailored for a corporate environment. These services have the bare necessity features, and cost only a handful of dollars per month. These VoIP providers have, along with their residential plans, a business plan.
