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...
