8×8 Business VoIP
The older version (‘Virtual Office Pro’) was entirely focused on small to medium-sized businesses.
But the new version (8×8 X) can serve enterprise-level teams. It provides all of the functionality as the old version with some new features too. The new version also has a new user interface as well as new applications.
There are 4 series – X, X2, X4, and X8. The upper range is really geared towards larger businesses. It is available as a desktop, mobile, or browser client. One of the neater features of this product is that if you make a call through your mobile phone, the customer will see your office number (if you so choose).
