Re: [hylafax-users] ISDN-BRI vs Analog DID: Hardware recomendations / Automatic routing

Also, do I have any other options for automatic routing of faxes?
The common automatic routing options that I know of are...
1) Distinct Lines and Devices
This is functional, but is rather costly for a 20-line setup where you
seem to be doing fine already with 2 lines.
2) Subaddressing
This works like a charm and requires no additional hardware, but it's
nearly impossible to educate the people who send faxes to you how to
send it... even if they do have fax equipment that supports sending it.
3) Routing on TSI
This also works well and requires no additional hardware, but it
requires maintenance work on the part of the HylaFAX administrator
every time a new fax sender sends a fax. And, hopefully your senders
use some distinctive information in their TSI. The big downside,
though, is that the sender doesn't choose where the fax is going. So
they can't send faxes to different routes on the same server.
4) Routing on Caller*ID
This also works well, but is nearly identical to the pros/cons of
routing on TSI.
5) Routing on DID/DNIS/DNID
This is usually what people want: distinctively dialed numbers for each
route. The downside, though, is that it requires special lines and
hardware. In your case where 2 lines have been adequate for 20 routes,
I would think that "analog DID" would be more appropriate than a
fractional T1... unless you can get your fractional T1 at around $100
per month.
6) DTMF Routing
You need a PBX (that knows the routing, probably from DID) involved in
this one. This is also called "two-stage dialing". The PBX rings the
line, the modem answers the call and waits for a series of DTMF
digits. The PBX sends the routing digits, and then the PBX puts the
call through. This works well also, but it pretty much requires that
you have in-house DID capabilities already... just not the DID-capable
fax modem.
7) Distinctive Ring
The telco rings with a different cadence for each dialed number that
terminates on your line(s). This works well, and added functionality
for this purpose was added to HylaFAX in 4.2.1. There is still some
codework to do to get the distinctive ring identification passed
through to FaxDispatch, but I'd be willing to do that if someone wanted
to step up and say they were willing to play guinea-pig for me as I
tested my development work on them. I think that distinctive ring is
limited to 5 different cadences per line, though. So you'd need 4 or 5
lines to match your needed 20 routes. That proably will end up running
you nearly as much as analog DID.
