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