[VoIP] DP-compatible ATAs

[Shane Young]

Two in and two out is four.  Multiply that by the number of switches you have.

We have 6 EM switches in two buildings (Federal/ITT, Stromberg, AE,  
North, Western, Itec).

Supervison (reverse battery) generally (but not always) stinks with the ATA's.

If you want to use E&M trunks, your options with ATA's are dropped  
down to just about nothing.

Now, if you had a bunch of blank trunk plates for a step office, you  
could stick an ATA on the plate and put the can back on and it would  
look just like a regular trunk.  Regular trunks have ethernets coming  
out the back, right?  :)
