Re: [hylafax-users] Hardware suggestions to get Hylafax running?

Hey Lee,

Okay, so a run in the mill T1 Card would work.  I'm guessing with the lack of hardware on that OpenVOX, The server's CPU will be doing a little bit of legwork too?  Shouldn't be an issue for a dual-core Opteron anyways.  I'll run that by my Phone guy on friday and see what he thinks about the Rolm setup.

On the software side, Any asterisk resources I can go take a gander at that discusses this particular implementation?  I'm assuming Asterisk is being used in a very minimal config as an interface to the T1 card via this libiax mechanism I saw mentioned on IAXmodem's site.  Or does it handle more things, like the DID parsing and all?

W/r to IAXmodem, what's the resource usage per channel when idle and off hook?  Pretty minimal I assume?  I won't be using all available lines on the T1 anyways.  I only have two PRI's feeding the Rolm (46 channels), so I'll have to limit how many simultaneous inbound and outbound calls this thing can do.  Starting with my original 4in/4out plan is probably good then, and upping that after some break in testing if need be.

So that gives me a very good idea of the equipment I'll need to get something viable setup.  Now the fun part is a client that integrates with Outlook for mailmerging-to-fax (what our sales people use.  Ugly, I know, but I can't afford to re-train them on anything else really).  I figure since this is open source here, someone's gotten bored enough to cook up something functional in that nature...


Thanks for the tips!  I'll look more into this on Friday, as I'm at a conference all day Thursday.  Cheers all!,

--Josh

Echo cancellation is worthless (and possibly even problematic) for fax.

Yes, but if you have a single T1 you'll not be able to use more than 
23/24 simultaneous channels (off-hook modems) anyway... as you appear to 
already understand.

Thanks,

Lee.
