asterisk users - Mar 2006 - Asterisk and Hylafax, on the same box

Hi,
 
I thought I'd check in with people here.  Lets say I wanted to put together
a Hylafax server, and an Asterisk server on the same box.  And, for the sake
of making things simple, I wanted to use a single T1 board for both....
 
Is this possible?  I see Eicon boards are supported by both software, so
could I have Hylafax and Asterisk installed on a server with an Eicon card,
with channels split between Hylafax and Asterisk?  Or even just being
bridged by Asterisk to Hylafax, somehow?
 
Could I get away with just one T1, or would i need 2? (one for each
software?)
 
I know this question is somewhat open-ended, but Im very curious on how to
make the most popular open source PBX work with what seems to be the most
popular open source fax server (my perception: I`ve never tried anything
with Hylafax)

An iffy idea if you expect any volume of calls. When the CPU is busy
converting files to a images you may experience problems with call quality
and MOH quality, up to and including the call dropping entirely. 
 
Servers are much cheaper than the time you may otherwise spend trying to
debug this type of problem.

Yes.  I've not investigated the Eicon approach that you suggest below, 
but if you can get the audio lossless into Asterisk (Zap, ISDN, 
whatever) then you could use iaxmodem to bridge between Asterisk and 
HylaFAX.

I don't know if this would work or not.

HylaFAX has to talk to a modem device, so I don't know how Asterisk 
would bridge it to HylaFAX without some intermediary device like an 
iaxmodem.

You could have as many or as few as you wanted.

Yes, this is possible of course with the Eicon Diva Server PRI (T1) card.
This card provides a CAPI interface where you can connect Asterisk(with 
chan-capi) and any other CAPI based application like Hylafax.

You can e.g. configure chan-capi to use 20 channels and the remaining 
channels configured in Hylafax.
When you use a Eicon Diva Server with DSPs on board, you don't need to worry
about CPU power, because fax-receive is done on the DIVA card.
So you don't need to 'bridge' something here, it just works.

That's not entirely correct :)

With the help of iaxmodem (which works really well) its easily done!
Just detect the incoming call is fax and the route it to iaxmodem on fax
extension.

I agree we have this working also.
