| Hello
I am running an Asterisk, fairly recent version, connected to PSTN. I only
use IP Phones but now want to connect a fax machine to the *. Plus may want
to also connect the odd analog phone. People seem to rave about Sipura.
How are they better than Grandstream?
Basically, some pointers on which to use and why would be really helpful.

A lot, when it comes to build quality and facilities available.
Having said that, you should be aware that fax isn't really supported on
most VoIP connections. It may work, it may not, but it isn't guaranteed.

card, as Ivor states, trying to use VOIP devices for fax is rather hit

The X101p and X100p are as you correctly said are FXO this is for connecting
to the PSTN not to alog devices, To do this you need either an ATA or a
digium TDM400 card with FXS modules.
Personaly i have deployed fax using cisco ATAs and Hylafax, and the fax
being detected by * and passed over. I have found as long as you lock the
fax server or machine to a max of 9600 it works without a problem.
As to ATAs you pays your money and takes your choice. various ones are built
to a price point, sipuras new range a now in all plastic so wont have the
"quality" feel that the 2000 and 3000 had, but they have to get the price
down.

Ooops, I meant that it could be used with spandsp standalone

| Thanks for that. I am not looking to do fax over a VoIP link. Fax will go
over the usual analog trunk. I just wondered? If I plugged a fax machine
into a Sipura ATA and sent a fax via an Asterisk then would the fax work
over eg an ISDN BRI or PRI channel setup on the Asterisk?

You pay for quality. I have no complaints at all about my Sipura 2000,
it's the most configurable piece of kit I've ever bought, you can change
the parameters on just about everything..!

I would think that 60% of the price you pay for a Sipura goes in
profit not in the quality and build of the product has you say it
works great but so does the Linksys pap 2 at less than half the
price .

You've paid for air, hype and marketing spin. I'd be prepared to stake
my bedsocks on the fact that neither you nor 99% of users understand
the scores of incomprehensible parameters that the Sipura 2000 is
afflicted with.

I got the linksys pap2 (based on the sipura 2000) and agree I dont have the
faintest idea what most of the settings are for ... ive managed to muddle
through and with help of others currently have it set to give a uk ring ring
tone and have it working on both sipgate and gradwell.

The Sipura 2000 is no different than a lot of up market adsl modems
and modem routers most are packed full of parameters that most wll not
understand or use . I have just removed my PCI speed touch modem out
of one machine and re installed a Dynamode modem router in preperation
for a radical move I am going to be making very shortly and I reckon
Ivor will guess what that move may be .
Anyone fancy buying two Sipura 2000's less than six month old £ 45.00
each !! .

You'd lose your socks, I'm afraid.

No, and unless you can prove it, neither have you.

Do you know if there is a good guide to doing the above? (setting up
asterisk to talk to hylafax).
Can you use hylafax to send faxes with the above setup?
I'm presuming that this isn't using an FXS port and a modem.
TIA for any help you can provide.

If you want to use Hylafax, you will need a Digium FXS port to
interface the hlyafax+ modem to Asterisk
If you wish to use spandsp, then you'll need a Digium FXO port
(TDM400/X100p/etc)
I guess you could use a ATA, but the results will vary, with Digium
hardware it should work first time as expected

I wak planning on using a digium card (well 2 of them in total), I was
just wondering id the receiving fax function from * can use hylafax and
whether hylafax can use * as its modem. (removing the requirement for
the modem and one of the FXS ports).

| I'm not sure, but I think Hylafax needs a physical modem
I did hear something somewhere where someone was planning to interface
Hylafax with Asterisk in a way that doesn't require a modem, not sure
where I saw this

I believe there is a CAPI module for Asterisk and if so then
it's likely that you can present a virtual modem to Hylafax and
terminate the faxes into that. You'll need to verify this, but maybe
that gives you a starting point at least. It's possible that you still
need a CAPI capable device though if Asterisk can't create a virtual
modem device with chan_capi to terminate calls into.
