Re: [hylafax-users] DTMF Detection Followup

["John Dell'Aera" <dellaera@xxxxxxxxxxx>]

Correct Neil. But I have no control over the sending environment
so I cannot force the senders to hook up a touchtone phone as
you outlined just to route faxes within my organization. What would be
nice is if there were a way for the sender to easily re-enable the touchtone 
pad
temporarily on the fax machine or if there were a way for me to re-enable it 
remotely from my
modem. Unfortunately, both options sound highly unlikely, but thanks for 
your interest in my situation.
