I have a customer that has an Avaya partner phone system. They called me yesterday and told me that the caller ID is not displaying on the phones anymore.

This is a residential house

I’m not sure if the system lost its programming

They also mentioned that the police got a call from 911 coming from their house in the middle of the night and they were both sleeping

It’s been a while since I’ve been in programming on that system. I was just curious what programs I should be looking at

Thanks
