I successfully resurrected a Cisco 7940 phone from a bad flash (or at least I think I did). The problem is that I get no dial tone (or any sounds at all) through speakerphone or handset. The phone appears to be working fine otherwise. It can make and receive calls (although I can’t hear anything either way).
Could this be a configuration problem or is it just a faulty phone?
PS - I don’t know if the speakers/mic were working before the flash. I was basically sent a non working phone.
