asterisk users - Nov 2004 - Deploying multiple Sipura 3000s with Asterisk

I was thinking about using a couple of spa3k's for deployment in a small
office.  At 100 $US per unit it is very economical for three or four inbound
lines plus a few analog phones.

Can the FXO and FXS ports on a single spa3k be used at the same time through
Asterisk?  For example if I had an inbound call on the first Sipura FXO port
and routed to the FXS port on the second device both devices would be in
use.  If another call came in on the FXO port on the second device would it
be able to route it to Asterisk and to the first Sipura's FXS port.

I am located in Canada.  Can I pick up the Caller ID information coming in
from the PSTN and pass it along to the destination device?

I like the idea that the Sipura will fail over to the attached FXS port in
the event that there is a failure.

I am hoping this will minimize echo problems related TDM devices and
motherboard timing.

Is there any reason why this isn't an effective solution for really small
businesses?

Is there anyone doing this right now?

Thanks,

Geoff

Yes it can. It can be set up with a fxs->* channel and fxo->* channel, and
*'s dialplan used to accomidate those needs. Just be sure to turn off the
option to pass incoming fxo calls to the fxs port (forgot what the option
is called).

Yes, callerid will be passed to *, and * can pass that along to the fxs port.

In addition, if the ethernet cable is disconnected or the hub/switch looses
power, it will fail over as well.

I'd be careful with echo assumptions. The spa-3k is known to have echo
issues as well, and can be seen in various postings on the voxilla site.
They don't seem to be as unpredictable as the digium cards are though.

Others are. I'm using it slightly different for a home system. Inbound
fxo calls ring through to the fxs port, and the fxs port is registering
with *. That way, home user dials 911 it is not dependent on * (or anything
else); no user (spouse) training. But, I have a dialplan set up that says
any fxs-originated calls that start with an "8" goes to *.

So home-user dial 8-3000 it rings * extension 3000. Dials 8-1-555-1212
and the call is routed via * to Internet provider. Since the fxs port
is registered with *, sip phone x3000 can dial x3020 and all home-user
phones ring simulanously.

Hi,

Can you tell me where I can source one of these units for $100 ?

If anyone who lives in the UK knows of a British supplier for these units,
I'd really appreciate some info on that too.

Thanks, Paul.

Do you mean the 5th entry ?

i.e. this: http://store.voxilla.com/customer/product.php?productid=16144

What bells and whistles are you talking about ?

Thanks, Paul.

Hi,

You go to www.froogle.com, pipe in "sipura 3000", and look at the
third
entry in the list.

They seem to be selling it with some bells and whistles freebies too.

No help there, sorry.
