Partner ACS 103G4 been working flawless then the other day every line (all 3 lines) has a feedback type tone whenever the phone is in use. Reset module, same issue. The feedback tone is a constant low volume "beep".
Suggestions? Can I pull out the entire module and replace it, what replaces the 103G4 that still keeps it plug and play?
Thanks all!
