I have a IPO 500v2 with 9.1 installed and have all incoming calls routed to VMPro Module VM:AutoAttend however about three times a day I get a specific caller that somehow get routed to the hunt group. I have asked the caller what he hears when calling and he says he hears the company greeting and then enters the extension number like 108 the group number is six digits and starts with 796xxx so he cant be dialing the group. What is the cause of this? What am I missing. Driving me in circles.
