Precision : My phones are Trillium Panther 612...

I need help to re-configure the main module. The phones were working great, then, this morning, for no reason, their setup is all changed.
Before, only one phone would ring, the others were silent, and the fax line would remain silent when a fax comes in.
Now, all the phones rings, even when a fax arrives.
How can I fix this? I do not have the programming sheet.

Thanks for your help.
