I have a new customer with a hacking issue. I do have some experience on the Nortel systems , but I am more experienced with Panasonic. Its seems someone is calling in and calling back out using my customers numbers to solicit people. I have gone in to the Callpilot and turned off outbound calling option in class of service (1) & (2) which is what Mbx's are set too. Does anyone have any thoughts ??

Thanks
