Using the 2811 for Fax

I have a 2811 that I want to put all my faxing onto. We have a dedicated PRi for FAX that will be connected to this router and I want to create the Analog (FXS) extensions off this router. I have the router which already has an HDV module with the 1MFT-T1-DI in it.  It also have 16 DSP channels.  I did the sh voice dsp voice command and found the following:

brs-Voice.GW_1#sh voice dsp voice

So I will buy the FXS WICs: 4 VIC3-4FXS/DID so this will give me the 16 analog ports I need.

Does anyone see a problem with this config?

If you want to have 16 analog ports and an E1/T1 PRI, 30 or 24 ports, in the router you need to have more DSP resources. Please use the DSP calculator to get the needed amount.
