This is a great PBX - I use only a few of the features for I use it as a call center robo call challenge system. I have the auto attendant programmed to tell telemarketer to hang up and drop us from their call list and to press 102 to teach us. It works great!
Great for have you own personal phone system with extentions. Instructions are clear with many features. But if you do not want to be bothered with features the system will work right out of the box.
Great product for a home office or multiple home phone household.
It's a great product which for the home owner, can block unwanted robocalls. Or if you have more than one line in the house (or more than one telephone), you can have multiple "lines" with just one phone number.
