24 channel, fixed FXS card w/EC.
The Rhino R24FXS-EC is ?ready to roll? with two incredible feature differentiation 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 R4FXO 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. Using Asterisk? Rhino Open Source Telephony PCI products allow you to utilize analog phones and wiring in conjunction with leading-edge Asterisk technology -- without having to buy expensive IP telephones. Why go IP when you can save on installations by using your existing wiring? With Rhino you can use lower cost analog phones with digital features and guaranteed T1 voice quality, all while enjoying Asterisk VoIP technology for off-premise connectivity.
