-= Pete Replied to Arthur Marsh about: Timed modem calls - warning confirmed =-

G'day Arthur

 AM> (V.32/V.32bis/V.34) answering a call and pass this information
 AM> on to measuring/billing software by means of a software upgrade
 AM> only.

 PC> Does HST have these 2100hz tones if not it may be a way around
 PC> the time charges.

 AM> If it were a HST-only modem, it would probably answer with 2100
 AM> Hz *without* phase reversals (or possibly even the Bell 2225 Hz
 AM> answer tone, which I encountered once when calling South
 AM> Africa).

 AM> If it supports V.32/V.32bis/V.34 it would answer with 2100 Hz
 AM> incorporating phase reversals which would be detected by the
 AM> echo cancellers.

So two Couriers in HST mode might get away with it.

     Pete.
