I like that it works with my existing phone number in order for me not have another line or service just so i can use this app! It's easy enought anyone who knows how their computer/phone system work could figure out what they need from there own knowledge base but if you don't know anything about computers then its hard because some things aren;'nt explained well at all which makes learning difficult (i'm talking specifically when first starting).
If your looking into using an application such as real pbx make sure thats something u want before purchasing otherwise get someone else help since most people would probably say no even though everyone says yes haha! Easy way around getting calls routed through our business account instead of personal one we had was by setting up multiple lines under different usernames within same email address & password combination - very helpful once set everything worked perfectly without any issues!!
