We are always adding new features to the user portal and quite often we just roll them out without any fanfare. This new feature is so exciting that it not only rated a blog post, but a how-to video as well! Sub-Account extensions now allow you to do 4 digit extension -to-extension dialing (for free) between your sub-accounts. If you are often calling your own DID’s, this will certainly save you some money. The groups part is for display purposes when managing your sub-accounts. Take a peak at the video and you can see how it all works.
