First off, I am totally unfamiliar with phone system operations, setup, etc. in general, but am smart enough to figure out just about anything thrown at me. What I have is a controller, model #103R 100-240. The bar code label shows 700316474 103R1 R7 and s/n 061622610840.
I'd like to add an on hold message that I have saved as an mp3 or wav file. Is this possible with this system and what are the steps to making this happen?
TIA
