Cisco Voice Gateway Router

I currently have a 2811 router with two FXO Cards and a PVDM2-16. We are going to upgrade to a Voice T1 as we are in the need of more phone lines. Now with a T1 this brings 24 channels meaning I can have 24 simultaneous phone calls right? Now I know I would need to upgrade my PVDM2, so a PVDM2-32 or a PVDM2-48 would suffice right? Then the only other thing I would need would be a T1 card for the router. Would this part number be correct? VWIC2-1MFT-T1. So in the end I want to use the same 2811 router, but just get the modules for the router that I need to support the Voice T1. Both the T1 card and the PVDM2. So would I be right in saying that the following would work:

PVDM2-32 or a PVDM2-48
VWIC2-1MFT-T1

I just want to make sure I order the right parts. I've never used a Voice T1 before.

VWIC2-1MFT-T1 is correct

For PVDM use this DSP calculator from Cisco

Thanks, I've used that site and I know that a PVDM2-48 will be more than enough. Even though a PVDM2-48 is more than I need at this current time, I want to get a card I can grow into, and I found one for the right price. Having a card that will support more channel's than I actually need won't hurt anything right?

No, it won't of course

I didn't think so, but Cisco told be I shouldn't have more channels than what I am going to use, which doesn't make sense because I have a PVDM2 now which supports more channels that I currently use.

My last question is regarding VIC2-4FXO cards and the VWIC2-1MFT-T1.

Will the Cisco 2821 Router support 3 VIC2-4FXO cards and a VWIC2-1MFT-T1? I know the PVDM2 has onboard slots on the the mother board so it doesn't take up a slot.
