It's the fax's answer tone that kills the echo supressors, some as a
modem's answer tone.  The tone you're thinking of is CNG tone (stands
for 'calling' tone) - and you're correct, some of the fax/voice/modem
switches use that tone to direct the fax to the proper device.  

If you're using a REAL fax machine, be sure to try automatic mode -
as opposed to manual mode, where you pick up the handset, dial, wait
for an answer, and then hit send...  that doesn't send CNG.  Auto 
mode is where you insert the pages, enter the number, and hit send
(while keeping the handset on-hook all this time...).
That DOES send CNG on most real fax machines - and the fax modems and
cards I've tried also send CNG.

Some of the fax switches will also accept a touch-tone digit or digits
to switch the call.  If you continue to have problems, you might ask 
the recipient what his switch does.
