That depends upon the type of central office equipment you have. 
While you're hearing the call-waiting beep, the far end hears
silence.  This looks like no-carrier to the far-end modem.  The
duration of the silence will be the duration of your beep, plus a
little.  This means that in some cases, re-programming your modem to
ignore a short carrier-outage won't help you unless the far-end
modem is similarly re-programmed.  The *70 option is probably a
better way, if it's available.
