I'm wondering if anyone out there is using fax and voice on the same
line. In the past, I've used mgetty+sendfax and vgetty to accomplish
this, but the facilities for receiving faxes with mgetty are no
where's near as complete as they are with hylafax. I'm thinking that
since a majority of the calls would be voice calls, that I should have
vgetty handling most of the work and somehow hand off to faxgetty, but
I've not found specific info on how to accomplish that.
Please note that I did search the list and found several mentions of
people trying (mostly unsuccessfully) to get faxgetty to hand off the
calls to vgetty.
You probably are accustomed to "adaptive answer", which tells the modem
to answer the call and then try to deduce whether or not the call is a
fax call, data call, or voice call. HylaFAX faxgetty would then take
that deduction and pass the call on to whatever the appropriate getty was.
Adaptive answer is problematic, though, by nature, and it can cause you
to have missed faxes and such.
HylaFAX can be configured to do this, however. There are people that
have done it, but I'm not one of them.
What you *probably* should do, however, is to get "distinctive ring"
from your local telco provider. That will give you different numbers
for your fax and voice calls, and the line will ring with a particular
cadence depending on the number the caller dialed. Modems that support
distinctive ring can detect this cadence and tell HylaFAX which it is,
*without answering the call*, and HylaFAX can then hand off the call to
vgetty or whatever. This method avoids the pitfalls of adaptive answering.
I get so few faxes that I could not justify spending the extra money on
a fax line. I'd be better off subscribing to one of the online fax
services if I have to go that route. I never really had a problem with
vgetty answering the line and determining if it was a fax or voice call.
That's why I thought if vgetty was doing the answering and handing off
to hylafax, I'd be better off. Maybe not though from what you're saying.
I guess I could just buy a second modem and one of those automatic fax
switch devices. I'm just trying to keep the total package small and the
cost down.
