Great product, the setup provided by OfficeTree gives a professional impression of the company you are calling at, so when someone calls the line, they are prompt with a menu where they can chose from a 1, 2, 3 options. They offer an on hold music and the voice that speaks is very clear and professional.
You can also choose your own phone number which is great if you are looking to add letters to your line (ex. 1 800 123-BEST), etc...
