One of our locations is getting repeated calls from an odd number. The number is 81 XXX XXX XXXX. When you answer the call, it is a lot of heavy breathing, and some circus music.
Aside from the creepy factor, this is happening every couple of minutes so it is beginning to be a business disruption.
We are using an MGCP PRI at this site.
I have contacted telco, and so far no help. Any other ideas as to what we can do short of changing numbers?
