detect phone or fax call |
|
|
Hi all,
I've winXP pro, and a sportster flash external modem.
It's a voice/data/fax modem, and as I've only one phone line, I'd like it to
detect and answer only if it's a fax or data call. If it's a phone call, he
shouldn't answer.
How it is possible to do so ??? it's there any program or configuration ?
Please help.

IMOE it can't be done. Until the call is answered there is nothing different
about the call/line that indicates what the calling device is.
OTOH your telco should be able to provide (for a rental charge) a distinctive
ring attached to a second number on that same physical line. Devices are
available which respond to the DR ring cadence and respond accordingly. Some
modems have DR capability, but on those I am aware of this is simply answering
the call and passing on the DR value to the host software as a parameter.
Have a look at www.natcomm.com.au for the FAXMATE as a typical device for
steering a call based on the DR. |

What 'budgie' said is good advice and I recommend it, but there also used to
be devices that would answer the call, listen, and then route the call to
your FAX machine, modem, or phone depending on what it heard. I hate those
devices because, in the days before anyone could get dial-in internet
access, I ran a Fido BBS and UUCP mail site that delivered mail by making
direct phone calls to other sites who would pass the mail on, etc. One of
the sites I called frequently installed one of those devices and then the
administrator left on vacation and, true to Murphy's Law, his computer
crashed almost before the sound of the slamming door had faded. For two
weeks, my computer called his countless times every night, and a charge was
incurred because the device answered the call... but, when it sent ring
voltage to his modem, it didn't answer, so there was no sound to let my
modem know that it had indeed gotten though (if it had connected to a modem,
for instance, but not been able to strike up a conversation with a computer
at the other end, it would have quit calling after a few bad connections per
night.) Since long distance was far more expensive back then, the result
was a pretty inflated phone bill!
