[hylafax-users] AW: Dispatching in any way

["Lumpp, Wolfgang" <wol@msc-ge.com>]

Hi,

a howto is there:
ftp.aeccom.com/pub/fax4i4l/howto/v1.10/fax4i4l-2.html

and also a message from Yan Seiner:
OK, I can resist anything but someone calling me a "charitable soul".

DID is pretty simple.

Ideally, you need ISDN/PRI, a T1, or E1.  The setup messages in these
contains both the Caller ID and the Called Party ID.

Now you need a piece of hardware that can report those two.

The Eicon Diva Server line of products works wonders.  The latest
drivers (6.0?) have enhancements for faxing that specifically address
hylafax.

Now you need to tell the drivers to report both the Caller ID and Called
Party ID.  For this you need to RTFM to get the correct command.

Then go into the hylafax config, set up CIDName and CIDNumber to
correspond to the string returned for Caller ID and Called Party ID (OK,
this is somewhat of a kludge, but it works), read the documentation and
scripts for faxreceive so you can route faxes based on CIDName and
CIDNumber.

Done.

Now, if you don't have ISDN/PRI, T1, or E1, it gets really, really
complicated.

In the US, AFAIK, only a handful of companies support MSN on ISDN/BRI;
even so, MSN only gives you 10 numbers for the ISDN/BRI circuit.  In
Europe, MSN is supported, but again, finding hardware, etc. etc. is not
easy.

I have not even looked at analog DID.  It apparently can be done, if
your telco/PBX supplies the requisite tones, and you can find a fax
modem that supports caller ID and called party ID.

My recommendation:

use ISDN/PRI if at all possible.  If you need to "fake" an ISDN/PRI to
your fax, look at the Adtran Atlas 550; it can take a single ISDN/PRI,
and split out 3 PRIs, 4 BRIs, and 8 POTS lines, route calls between
them, and do all sorts of magic.

It ain't cheap.  An 8 channel Eicon Diva Server ISDN/PRI is about
US$2,600.  An Adtran Atlas configured the way I have it approaches
US$5K.  (I use it for a bunch of other things.)  And the PRI from the
telco is big $$$$ - we pay nearly $1,000/month.
