i have a 7400 v4.46d that keeps receiving phantom calls from some where maybe inside the system. they have a PRI & SIP trunks. we have SMDR capturing the data daily & the digits that are coming up from these calls are (11001 & 12001) these call the operator group & nothing is on the line & then it hangs up on operator after a few seconds. This just started happening about 3 months ago & its not everyday but frequently during through out the week. they have had this setup for a few years now. Has this happened to anyone else?? I'm not sure what i can do to fix this.... Help.
thanks
