Here are links to the modules that are needed for this base card:
Rhino Dual FXS Analog Module
Rhino Dual FXO Analog Module
The Rhino R8FXX-EC is the first analog card for Asterisk that eliminates "bit-banging" the PCI bus. Other manufacturers have been known to have problems with bit-banging. The R8FXX-EC has built in echo cancellation so there is no need to purchase a separate module. The Rhino R8FXX PCI analog card features a control element to remove all "bit banging" on the PCI bus, something that other manufacturer's have yet to solve! This Rhino feature significantly reduces PCI and CPU overhead.
Rhino R8FXX-EC Analog PCI Base Card with Built-In Echo Cancellation
Rhino's onboard echo-cancellation provides excellent voice quality and fast convergence rate. There is no divergence due to doubletalk and cancels multiple independent tails. The Tone Disabler disables echo canceler during voiceband modem and FAX connections. The echo cancellation module is a G.168 compliant line echo canceller, which meets and exceeds G.168-2002
