I am updating and combining a couple of routers. Router A is a 1711 router with a Single T-1 circuit. Router B is a 2611 with a single T-1 circuit and also a 2 port FXO card -both ports in use. The 2 ports are analog lines mapped to equivalent ports at a remote location.
I am moving to a 2801 with a vic2-2fxo and VWIC2-2MFT-T1/E1 with IP-Voice software. The Dynamic configuration tool says I also need a PVDM2-8. Do I?
