this # has been calling for 4-5 days now ...twice on the 8th .I called it back and it says the # is not assigned. grrrr.

This number has called four times. Nobody on the other end, when I call back nothing happens, just dead air.

I left a comment about this number a week ago and it called back again today on Saturday evening.  This is a market research company calling to ask opinion polls.  This was the first time anyone has ever been on the line.

Received call at 11:40 a.m., 28 June 2008.  Did not pick up because I was too busy with other tasks. Ringing stopped before my Telezapper had a chance to send an "out-of -service" signal ... it does this when our answering machine kicks in or when receiver is picked up.

Not sure if I've received this number before but will let the Telezapper deal with it next time if I can pick up before it disconnects.  I'm not convinced my Zapper works on all automated (computer generated) calls even though I have it set on full service.

If I'm unsuccessful, will try Dave's remedy.

I receive this call every few days after 6pm, and today (Saturday) it came in early afternoon.

Thankfully I run my own Trixbox (VoIP PBX phone system) and have simply added it to my blacklist, which never rings my extension and sends back the zapteller to the calling end. :-D

This number has called me several times, all around 6-630pm.. I have called back and it just tells me not in service.
