I like that this app can be used throughout my business day with minimal effort from me as an employee! The interface could use some improvement but nothing major - not enough buttons or options at times when you need them most (e.g., dialing out). This helps our employees communicate quickly during their time away from work so they feel connected even though we are physically apart. My coworkers who don't regularly utilize VOIp typically do complain about being able to easily access us while working remotely because there isn’t much choice around here yet compared to what's offered by competitors such as Vonage etc..
