Rhino R4FXO-EC

The Rhino R4FXO-EC is 'ready to roll' with two incredible feature differentiations over the competition - on-board control element, and on-board Echo Cancellation circuit. The control element eliminates PCI bus 'bit banging', which means that the R4FXO-EC requires less CPU power, and more Rhino cards can be used in one computer over alternative, antiquated solutions. The Echo Cancellation circuit provides echo protection no matter what, to ensure that calls are clear, crisp and echo free.
