[cisco-voip] Cisco 2800/3800 Wic cards

[bababooey at cox.net]

Can someone help me out, can I put a VWIC-2MFT1 in the HWIC slot of the 28/3800 series routers?  Or do I need to add onboard DSP modules to support them.
Is there a good link to describe this?

I need a 2800 with on T1 interface to a PBX.  What is the best config, 
router-vwic+dsp's  or
router-nm-hd-ve-vwic (dsp onboard nm card)


Thanks for your help
