I have a customer who keeps getting 101 alarms. I know that this is a very generic alarm that means there is a hardware issue somewhere. The MiVoice 250 has only been in operation for six months. One phone I replaced the jack and the line cord, and another I actually ran a new Cat6 cable put a new jack on it, with a new line cord to the phone. I also upgraded the software from 6.3 SP2 to 6.3 SP3. I am hopeful that these changes may help. The wiring at this particular customer is very old and runs through multiple IDF's. The dilemma is that the error screen does not tell which phone is producing the errors. I have included a screenshot of the alarm. If this keeps happening, I am just not sure what to replace next. Any suggestions?
