Fine for calling out, though it has a bad case of Form Over Function. Interface gaudy and confusing. Cant seem to hold a connection to the server so inbound calls rarely make it. I cant make it show a working keypad (you can get one, but the # key doesnt seem to do anything) during a call (for menu systems, pass codes) and voipswitchs website pops up an overlay that wont go away, so the website is no help either.
