They're coming in via our TDM tandem connections.

Are they coming in via your carrier(s), or are they coming from random IPs?

We've been getting "empty" calls for years. BY empty, I mean there's no audio 
there at all. They're calls from all over the place (I don't think I've traced 
them all down). We've had them sit on the line for hours (back when our IVR 
permitted that). 


Okay, I'll just deal with it. Now they're hitting our customers too. 


To me, it's more annoying than active scam calls because there's doubt if it's 
real or not. I assume every call not from a current or prospective customer is 
a scam, so from the content, it's easy to tell. 




How are others handling these calls?
