[Hai-users] VoIP compatibility

[Dudoussat, Scott A.]

Where exactly are you measuring the voltage?  You should have one probe on the "GRN" and the other probe on the "RED" terminal under the section marked "PHONE" on the Omni controller.

With the red probe on the "RED" terminal and the black probe on the "GRN" terminal, are you measuring a positive or negative voltage?

Do you know what the panel wants to see?

Metering right there, I get a solid 49.67v on hook, 11.35v off hook, and 
flashes in the 5-12v area for an incoming call.  Seems pretty good to 
me.  Yet, the panel reports a phone level of 0 for both on hook and off 
hook.  Only time I see a change is for incoming calls.

Seems like the panel isn't working right.
