Do you know of any problems that would be caused by using this 
configuration on an Asterisk server that is doing _nothing_ but Zaptel 
and IAX? In other words, our PSTN gateway box has Zaptel connected to 
PRIs, and IAX to other carriers, as well as IAX to our Asterisk PBX 
server. In this configuration, nothing is being directly played to 
Zaptel channels, it's all Zaptel<->IAX.
