same issue as described above. try calling the number back and get message - "your call cannot be completed as dialed" -  argh

Phone rings - no one there,. Can't even get a dial tone when trying to call back. Never had this problem until I put our 800 number on our new website.

I DONT KNOW WHO THEY ARE BUT THEY WILL NOT  GET ALOT OUT OF ME AT 4 AM

Received silent call on our toll free number at 4:24am.  I have been receiving numerous silent calls on both our toll free number and local office number every day.

This is probably a caller ID dipping fee scam.

I am beginning to suspect that our toll free supplier, Kall8, is somehow involved.  I had a toll free number that started receiving these silent calls.  I got 3 additional vanity toll free numbers to replace the old number.  As soon as I placed one of the new numbers in service, it started receiving silent calls and the silent calls to the old number stopped.  At the same time, I started receiving silent calls directly to our local number to which the toll free rings.

If you have a toll free number (especially Kall8) and are receiving silent calls, please see
