I have a customer that is having thier system hacked. I checked for rougue and unsecured mailboxes. There are no boxes with outdial enabled. How are the calls getting out??? And how can I make them stop?
Thanks
 
Just so you know, when the AA answer on a NAM press 9 and the alternate greeting starts to play, press 0 and the local operator will answer. You can then place any toll call you wish via the operator. That is why you must build a filter and block at least 0 and assign it to the vmail DN's. The voicemail ports are just extensions and need to be considered when installing the system.
