[Asterisk-Users] Phone attached to Sipura SPA-1001 has no ring

[Ian Pattison]

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.

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?
