I have a user who has the 616-EASA-Phone system in their home. They are reporting that during the night different handsets will randomly start ringing with no incoming call on the other end. It has been working without issue up to 3 weeks ago. There were some storms around the same time. Could lightning have caused an issue with the system? They report that the issue does not occur during the day, but I do not know if that is just because they are not home constantly during that time.

Thank You

Does anyone know of a Minneapolis area based Panasonic phone technician?

There are fellow technicians that "follow" and get a notification of everything posted in that location.
You can see the format that makes it simple. Just add your name, number and system type.

First give your customer an award for having such an old system still working!

I had a similar issue that occurred every night around 11:30 for one customer.

A friend I knew worked for Verizon in West Virginia. He said to contact Verizon and ask if they are doing any fail-safe polling on that line. I forget what the actual name of the service was, but Verizon would poll various pots lines around the area during the middle of the night, basically random checking for lines that might be down, etc. This was done by sending a pulse along the lines and looking for reflections I suppose. The pulse was a very short voltage that - if reaching a "standard" 2500 set bell, it would just ding once. BUT when the pulse hit the pbx, the pbx thought it was an incoming call and started ringing extensions around the house.

I was able to call Verizon and they confirmed that the number of the line in question was on the list for receiving these tests. They removed it from the list and the problem went away.

I spent a week leaving a laptop at the customer's home to track all incoming calls from the SMDR. After a week we did see incoming calls but there was no caller id. Luckily I had a knowledgeable friend!
