I like how easy it is for me as an individual user, or even in small groups (like my team) with multiple users using different devices/browsers - we have no problems syncing up our accounts! The customer support has been great so far too!! There isn't anything at this time but if there were more people would love them all over again.
Great product overall- super simple integration process & very helpful staff when you need help getting setup etc.- they are always willing jump right back onto chat w us once setup was done :) Definitely give call spree another try before writing off their service completely because other providers do not provide such fantastic services compared either price wise OR ease / simplicity level offered by CS Reps! We use CSP primarily now instead o traditional outbound methods since its much easier than having phone calls go through voice brokers who charge exorbitant.
