I have been using this product since 2011 when it first launched as an online version only tool that could be accessed from anywhere within or outside my office/company network at anytime day OR night via web browser! The interface has evolved over time but still remains simple enough even by those who are not familiar how things typically would look & feel while working remotely (i am one myself). There really isn’t anything about callofservice i dislike so far however; they do need more training materials available such us videos etc.. It does help if you already know what most functions can mean otherwise just try looking around their website before purchasing because there may very well exist other tools better suited towards certain tasks depending upon ones type(s) business services offered eetc...I highly recommend anyone needing remote access solution should definitely check out COS!! As mentioned previously above some features were lacking.
