This comes up as TELSEL and they call all the time!

none just a ringing all the time

Called two days in a row. Why..what is the purpose of the call

THIS NUMBER CALLS ALL THE TIME-  NO ONE ON THE LINE--THEY HANG UP
VERY ANNOYING  WHAT CAN WE DO ABOUT IT?

Received call from: 1-904-685-4439.  Caller ID:  TRUNK GROUP 904
When I answered, person stated some nonsense about energy efficiency savings?  As soon as I said I am NOT interested (and tried to say add to DO NOT CALL), they hang up before I can say that!

I am ALREADY REGISTERED with National DO NOT CALL registry!  This is COMLETE NONSENSE, as apparently, they can STILL CALL??   I report it on that site, and oh, I get call next time from DIFFERENT number!
