[Asterisk-Users] Deploying multiple Sipura 3000s with Asterisk

[Geoff Nordli]

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
