| GXW ATA and analog extensions
You're darn right the Grandstream GXW4008 doesn't support lighting message lights on analog extensions.
Where would it get 80v from?
When I started this thread, I didn't know how analogue extension message lights were turned on, and wondered if there was some kind of kludge or workaround. Once I found it required the application of a steady 80v across the analog pair, I gave the idea up.
I wonder what voltage is required to ring an analog extension?
I imagine it would be some tens of volts.
And where does a GXW source that voltage from?
Just passes it through from an Asterisk box?
But they run on low-voltage DC also.
