If I am not mistaken, of the three options only the VWIC is supported on the 2801. It is voice and data capable.

The VWIC supports ISDN for voice.
Remember you will also need PVDM2-xx.
No voice configuration can be done without it.

I have read that data sheet already, but I do not see any clear mention about ISDN.

You may need additional memory depending on how many modems you want. When I used the Dynamic Configuration tool I got this message:
Please refer to the DSP Calculator at the following URL to make sure you have selected enough PVDM resources: http://cisco-images.test.edgekey.net/cgi-bin/Support/DSP/dsp-calc.pl. Note, Cisco 2801 supports maximum 30 digital voice calls with VWICs.
