The ability to have multiple call centers at once with one number allows me as an agent more flexibility when scheduling calls or taking messages from customers that are not local (which I can't do if they're using their own PBX). It's also easy enough to use without having any training since it has all of its features built-in so you don't need additional software like other systems require. There aren’t many downsides but there could be some improvements made here such as adding mobile apps/widgets etc., which would make this even better! We've been able solve our problems by being connected 24 hours per day via video chat while we continue working remotely through Zoom meetings during COVID times - no office space needed anymore!!
