I have a mitel sx-50 with an alarm of A 13 0044 then a date of course.

I know that the 13 means to check wiring and found some corrosion at the wall, I am going to replace with a new termination block and wall plate and new jumper to phone.

The problem is, with the phone disconnected even at the 66 block I am still getting the error. Wouldn't the error go away if I have the wires disconnected at the 66 block then clear the error at the console.

Thanks
Jeremiah
