[VoIP] DP-compatible ATAs

[Steph Kerman]

I wonder just how well your typical ATA works in an environment full of 
1 amp 400V back EMF spikes.

I also wonder how many people will have trunks to so many switches and 
need independent trunks at that.  Most SXS systems can have trunk 
outlets from a selector level of different exchanges multipled to the 
same OGT.  I'm even sharing trunk equipment between my SXS and XB 
systems.  So unless the traffic requires it, it's not obvious to me what 
is accomplished by having an independent pair of OGTs to the * box from 
each distinct exchange.
