I have a customer with a call manager express and a unity express. They have an 800 toll free number that rings in to an auto attendant on the CUE. The problem is something called toll fraud traffic pumping. The caller, always from a different number, reaches the auto attendant by dialing the 800 number. They then somehow manage to keep the line connected for up to 12 hours by somehow staying in the auto attendant. I opened a TAC case and was informed that it is not in Cisco's hands to create a way to disconnect a call that is connected to the CUE. I need a way to have a call that stays in the auto attendant or voicemail after 3 to 5 minutes. I can't see a way to do it in the auto attendant script. Can someone help with a method that will disconnect the caller if they stay in the CUE for a period of time?
