[VoIP] DP-compatible ATAs

There is an interrupt issue with the X100 and the way it is used with 
Asterisk and Linux and the DSP in the specific modem, all in 
relationship to specific motherboards and their bios and sharing of 
interrupts
The modems you mention are not usable in this application, and the way 
Win2K controls them also do not apply.
Some machines can use 2, and some have reported even 3, but unless one 
wants to spend days going through piles of motherboards and 
reconfigurations, best to stay away from that all together.
As to the ATA's, will the FXO circuits pulse into your switch, or  will 
the target accept TT?
The FXS circuits probably will not accept pulse
You may want to search the Asterisk users list for information and 
gotcha's on these units.
ISTR there were some issues related to them, but since I had none and 
didn't expect to, I can't address that in more detail
