Question about IBM Corded Phone IBM412CID
I found this site because MY phone won't stop ringing. I was so happy to see your problem posted, because I was hoping to coattail for a solution. BUT then I found an old folded printout (2-28-03) of a FAQ from TTSystems (now out of business, I guess) that solved the problem. Here it is: The extensions have to be reprogrammed after a power outage. (My trouble started after a big electrical storm knocked out power to our building.) I guess the same is true of loss of power for any reason, maybe even unplugging them if no batteries, etc. Anyway, each phone's extension defaults to 11 after power is lost. The ringing happens because all the phones have the same extension number--11. So, reprogram them so that they have an extension number from 11 through 22. 1. Press [STORE] 2. Press  3. Enter the two digit number you wish to assign to this phone. 4. Press [MUTE] A short ring will be heard to signal successful programming. I am so ridiculously happy that I fixed this. I hope it works for you.
