I like that a user can use their own headset, and not have to worry about the quality of mic or speaker while on call with someone in another country. The interface could be easier for less tech savvy users but otherwise it works very well. We are using this service for multiple sites across our organization (both internal and external). As such we need an easy way to connect one site's meetings room to others without having to constantly re-join/reconnect each time. This allows us all to participate from anywhere at anytime! Great product - definitely worth checking out if you're considering similar services! For now, what is great is that there isn't much competition so price should stay relatively low once they catch up. Benefits include being able to join calls from home which helps reduce travel costs, as well as allowing staff who aren't present to still take part by joining via.
