Review: Nice system, you get a lot with no extra fees - Nice phone brain system, not plug and play, watch videos on how to program it.
Review: Great for Collectors of old phones as well! (*With use of an ATA that supports Pulse Dialing.*) - Very easy to program and allows use of older touch tone phones as well. For rotary support one will need to get one of the ATA's that support rotary pulse dialing. I ordered the ATA-818 to work with this PBX allowing rotary phones within my collection to work within this phone system. Over all its has allow of features that would used be licensed features on products offered by major brands. This device is perfect for my needs. It also offers video/chat Skype like program called WAVE for devices that support it (Smart phones, tablets and PCs)
