You said you heard modem negotiating tones.
That means they would be likely using a POTS codec like a Tieline 
http://www.tieline.com/Tieline_04/codecs/CommG3.html
or Comrex Martrix
http://www.comrex.com/products/matrix_codec.htm

These boxes do a surprisingly good job of sending "studio-like" audio 
from a remote site and the studio (and back for cueing purposes) with a 
connection speed of 24 to 33kbps over a standard phone line.

One side-effect of the heavy data reduction needed is that is imposes a 
delay of 1/4 sec to 1 sec in the audio.
Is the delay you heard of that order (as opposed to the typical 8 secs 
for a "profanity" delay)?

Peter Smerdon
