Who would have imagined…

WarVOX is a web interface to an application that uses AIX VoIP protocol to make multiple calls simultaneously. Instead of doing live analysis on the live calls, it records them and post-process them to find patterns which would indicate the presence of modem.

One of the advantage of their analysis technique (post-processing and looking for frequency patterns) is that it opens the door to call aggregation. For instance, you may be able to flag a certain pattern as being a certain type of PBX (since the default automatic answers are all going to have very similar frequency pattern, even if it is technically a voice call) or other types of system.
