This was retail stock at a defunct electronics shop and consigned to an sale. Appears to work fine but I don't know what all of those connections are for so I can't test much, but it is offered as a working unit and guaranteed. Ideal for a small to medium sized business with paging and telephone connections but those could be useful at home as well when it is dinner time. Shipping by the most advantageous method either USPS or UPS, depends on where you live. May be picked up in person in Boykins, Virginia for no surcharge.
