[Asterisk-Users] TDM2400P FXS Only vs. T1/E1 to FXS Channel Banks

[Jonathan Feally]

Appreciate the thought on the handsets - but these lines will be going 
into an apartment complex - that is why faxing must work on any line and 
it must be analog.

The astribank will not be a valid solution with the number of them I 
would require.
