asterisk users - May 2005 - Phone attached to Sipura SPA-1001 has no ring

I hooked up a SPA-1001 with asterisk yesterday and all works well except 
the phone doesn't ring.
The phone I'm using has a LCD display so I can see the call come in. 
(with caller id info)
I can answer and complete the call but it's just not ringing.
The phone rings if pluged into a POTS line so it's not the phone that's 
the problem.
I've used the SPA-1001's web interface and the ringer seems to be
enabled.
Is there some setting I'm missing?
Or is there something special I have to set up in asterisk?

I have had the same issue with the SPA 1001 -- one phone refused to
ring, although it did on the SPA 1000 and others. A different phone
worked fine with the SPA 1001. I suspect the small SPA 1001 just
doesn't have enough ring voltage or current to drive certain types on
phones. Just I guess... didn't try to tweak the settings much.

I've had similar issues with TDM400P FXS ports and it turned out to be a
voltage issue. According to spec a North American FXS port (whether from your
ATA or your telco should generate a 89V, 20Hz AC signal for ringing. Some
systems try to use a low voltage ring (usually about 45V) which won't
trigger some phones.

Incidentally I have a SPA-1001 and it's giving me no problems.

Sounds like what I had.  My SPA-1001 came like this and was RMA'ed.

The ring voltage is adjustable in the advanced settings.  I tried both 
raising and lowering it to no avail.  It wouldn't ring any of my 
phones.  I don't recall seeing it generate callerid though, but to tell 
the truth I wasn't paying a lot of attention to that.

The web server status page would say that the phone status was 'Ringing'
while this was happening.  And if I picked up the handset while this 
was happening, the calls would complete.
