[Asterisk-Users] Ring power on Analog adapters

Hello,

I have a big old Fax machine that will only pick up a ring at 24volts and
20mA(minimum) ring[according to the technical specs manual]. None of my SIP
-> Analog phone adapters supply this:

Cisco - 50 volts
SIPURA - 70 volts
Handytone - who knows, but it doesn't work

can anyone tell me if there are any analog adapters or channel banks that
can send a 24V 20mA ring signal?

Also, does anyone know what voltage the Digium analog PCI cards send out for
ring?

Thanks,

MATT---
