no, its the mismatch between the analog DID device and the digital 
signal process coming in from the T-1.

the fax device is a multitech DID modem - they work with only a
"analog DID trunk line which supports the inbound fax calls and a 
regular loop-start line for standard inbound/outbound fax transmission."

however, apparently this is not what DID through T-1 is, which is why
i'm either looking for some sort of converter that is specific to and
retains the DID info, or a different modem (and perhaps hylafax, as
vsi does not support too many).
