We have an NEC SV8100. I have total access to the WebPro interface. We had a toll fraud hit us and now we need to disable all international calls (since we never use international calling) and remove any unused mailboxes and change all passwords. I do see in WebPro 21-05 Toll Restriction Class, 21-06-01 and 02 for the tables etc. The truth of the matter is, I have no clue what I am doing. The company that we purchased this from has gone out of business so no help there. On a side note, are there any training courses or online instructional sites/videos available? Thanks so much for any and all help!
