I have a customer in Collierville, TN that is having problems with international long distance hacking. I have always sold through the grey market using Hi-Line Supply and lately gotten tech support from a guy named Harvey. Recently Harvey and I went through the MICS settings (version 4ish)and he assured me that the only ways the calls could be made was from the inside. Since it is an AT&T PRI with Touch Tone as their provider and I suck at toll restriction I did what I have done for years. We had account codes added to their long distance. We thought that had it handled however the problem is back and they are telling my customer that the hacker is dialiing a 1010 code from the outside. I just spoke with my at&t rep he assures me the PRI is an old style non-VOIP. The customer just told me that AT&T tech support is telling him to check settings in his router which souds like a VOIP PRI to me. The truth is they have had about 5 different service providers in as many years and I can't get back in until 7 a.m. central tomorrow to see for myself. I put in my first phone system in 1981 and this is my first post on any forum ever so hope you people out their are kind to me. Thanks for any suggestions in advance.
