Help completing my Voice Lab..

I just purchased a Cisco 2811 Router 768 DRAM / 256 flash IOS 15.1 Adv CME v8.. Coming in the mail now...

Additionally, I have a 1721 router with a WIC 1T module (and one additional empty slot...). I have in addition, a WIC 1DSU 56K card, and a WIC 2A/S in a second 1721...

I have a 2 3550 PoE switches and 1 2950XL switch

I have one 7940 series phone....

I am not exactly sure on the purpose of the VWICs, how many I might need, and how many DSPs (FXO/FXS, right?) I might need to fill out the lab. In the Army, I had a month or two of experience with FXO/FXS cards, but only to feed a PSTN line in and get call routing out at the other end of the network... I am REALLY new to Voice..

I have a quad core home PC with 12Gig RAM..

I am pretty sure I can use the 2811, 3550, and the phone.. I am not sure what I can use from the rest?

So, to recap...

1 2811 Router 768 DRAM / 256 flash IOS 15.1 Adv CME v8
2 1721 routers
1 WIC-1T
1 WIC 2A/S
1 WIC 1DSU 56K
2 3550 PoE switches
1 2950XL switch
1 7940 series Cisco phone
3 7960 series Cisco phones - Purchased 3/25/2013
DB60 DCE/DTE cables
Quad core 12Gig RAM PC for VMWare
CISCO PVDM2-32 - Purchased 3/25/2013

I have a feeling I have a good portion of what I need, but not sure what I can/cannot use as far as the 1721s are concerned?

Thanks for any clarification you can provide.... Also, I assume that having Vonage for my home phone should not matter either way?

That's what I would go with.

Guys could you please clarify which version of FXS card is compatible with 2801 or 2811 routers.
According to Cisco table of "Software and Memory Requirements for Voice/Fax Network Modules and Voice Interface Cards"
Cisco IP Communications Voice/Fax Network Module [Cisco IP Communications Voice/Fax Network Modules] - Cisco Systems
VIC3-2FXS is required 2800 series.

The VIC2 series works with the 2800 series, but also the older VIC-4FXO and VIC-4FXS/DID 1st generation cards. Unknown if the VIC-2xxx cards work/recognised.

I don't think that's the case. I have a VIC2-4FXO card plugged directly into an HWIC slot on one of my 2800 series routers and it works fine, no need for modules. That's why there are called ISR's right?
