Multiple calls during middle of the night. No answer no connection. Not a fax calling.

Did not answer call since it provided no caller ID. I tried calling back blocking my # and the recorded message said that the C-Spire customer I was calling is not available for calls at this moment...try again later...

Fax machine. A few times a day, mostly evening time.

3-4 calls a day from fax line all hours of the day and night last 4 days.  really getting annoying

Unidentified fax message that comes in on regular phone line multiple times daily; sometimes immediately after hanging up.  Know it is a fax because of the trilling fax tone.  However, even when I punched in the fax code, the fax did not come thru.  On one handset it came in as "no number available"; some legitimate calls do come in with this designation so I can't just assume it is not a real call.  On other handset it came in as 1-(613) 736-4374/">(613) 736-4374/">(613) 736-4374.  I looked up this number in reverse directory and found it listed as:  Telemarketer_warning_icon-cdn-249803839ed444f5926091359d261737This phone number is flagged as a telemarketer(613) 736-4374/">(613) 736-4374Maineville, Ohio    Company: Agero    According to 86 People    Type: Fax Machine    According to 86 PeopleThis is a "JUNK" FAX ((613) 736-4374/">(613) 736-4374/">(613) 736-4374) sent by:Agero Motor Club formerly / Cross Country Motor ClubPhone +1 800-541-2262They are Hawking parts using Worldwide Parts SpecialsPhone 815-725-4400FAX    815-725-4446  or as:(613) 736-4374/">(613) 736-4374/">(613) 736-4374Country: CanadaLocation: Ontario (Kingston, Ottawa)details Phone Number DetailsPhone Number: (613) 736-4374Owner Name: On File - Click HereMost Current Address: On File - Click HereArea: , ON (Ontario)Phone Company: BELL ONTARIOSwitch: OTWAON10CG0Successful Match - Download your Results for (613) 736-4374/">(613) 736-4374/">(613) 736-4374 NowPhone Number:     (613) 736-4374/">(613) 736-4374     Search Date:     02/28/2013     Search Time:     4:52pm PSTArea:     (Ontario)     County:         Line Type:     Results:     Available (Confirmed)     Query ID:     953142719     Data Aggregator:     INT-II(613) 736-4374/">(613) 736-4374/">(613) 736-4374:Phone Type: LandlineLocation: Ottawa-Hull, ONHalf a dozen calls alone so far just today, 2/28/20123!  And it is the kind of fax that no one picks up an attached handset when you answer so that you can tell them they are faxing to a wrong number!

I'm getting these calls several times a day.  It's getting very annoying
