I have a similar situation today:
I have a phon number of 931-698-4964 calling several of my PRI 800 numbers. The problem is that this number doesn't exist! It is a Verizon number, and they say it hasn't been activated since Dec. 2003. Must be a spoof! The call duration ranges from .1 minutes to over 12 minutes. I've called Sprint and they are gathering information and getting me information how to contact the FBI. Anyway, I'm not having them block this number yet, but I do need to block this number from accessing the system for such long periods of time. I would like to just send a busy out the line once this caller connects. Can anyone give direction how to do this?
Thanks,
Ryan
