- AUDIO +
The issue that I have is that the 8038 phone, as I understand it... does not have a simple ON / OFF indicator for the OFF-HOOK condition.
I presume that the Digital UA Link on pins 3 and 4 of the RJ12 connector is a serial signal used to send this (and likely other data) out of the phone.
Is there a device I can purchase that simply decodes this and gives me an OFF-HOOK condition?
Does someone have a method to decode this signal?
- A circuit?
Anyone ? Anyone?
Flying to customer today... any help appreciated!!!!
