All phones in the office ring at the same time but no CDR data

I've got something weird going on in my Tokyo office. About every 90 days or so all the phones in the office ring at the same time and there is no caller id displayed on any of the phones. I have tried running CDR reports on both the phones and the Gateway and I come up with no data.

I have a total of 36 phones at this location:

31 - 7945

2 - 7911

1 - 7936

2 - 7937

My CUCM is running 8.6.2

My 7945 is running 9-3-1 firmware

My 7911 is running 9-3-1 firmware

My 7936 is running 3-3-21 firmware

My 7937 is running 1-4-4-0 firmware

Any suggestions?

Thanks

Hi,

If the caller id details are not appearing on the phones then the first option is to enable detailed callmanager traces on callmanager servers to which these phones register ( preferably all servers ) so that the call related details can be captured. It should show the gateway from which the call is coming in as well as calling party info.
