[cisco-voip] Big analog gateway?

[Matthew Saskin]

Both audiocodes and quintum make fairly inexpensive devices to do larger
scale analog to IP conversion.  On the cisco front, you can get pretty good
FXS density with the EVM-HD module in an ISR/ISR G2 - should be 24 ports per
EVM-HD module and you can put two into a 3845 as an example.  May not be the
cheapest way to get ~50 analog ports however.
