Rhino PCI plug-in cards satisfy the needs of Open Source Telephony (OST) applications, no matter how stringent the requirement. Rhino Open Source Telephony PCI cards feature Asterisk, Zapata and Linux tested software. Knowing that Rhino products are ready to perform right out of the box means that you can spend more time developing important customer relationships.

The Rhino R24FXO-EC is ?ready to roll? with two incredible feature differentiations over our competition - our on-board control element, and our on-board Echo Cancellation circuit. The control element eliminates PCI bus ?bit banging?, which means that the R24FXO-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.
