This number keeps calling, with no voice or message. Prank call?

We have about 30 calls a day from this number-we are a medical facility who are overloaded with calls anyway-seems to amp up in the pm-can somebody please unplug this bloody thing!!!!

want to block this no. (02) 8323 4300

This number keeps calling me each day. It is related to one of the bitcoin sites. I answered once and seems now I am on an auto redial list. I asked to be removed and am already on the do not call register but they don't care. They even called back inside 30 minutes one night and accidentally left a voicemail where I can hear them chatting.

Caller: SMART TALK NBN

Calls my private and business everyday no matter how many times I tell them I am not interested. Claims that they have deals that I don't want to miss. Surely there is a way to block them.

Multiple calls from this number... all fax type of calls if i hang up it just keeps ringing. i diverted to our work fax and comes up with a document for Pharmaceutical Society of Australia - there number is 1300 369 772

I receive approximately 3 calls from this number every couple of days. It is though it is a fax machine as no message is ever left, only a few beeps. It is incredibly annoying. I have tried calling the number back but it just rings out. I have even sent a fax to the number asking them to stop trying to send a fax ( if that was what they were trying to do).

Calls from this number with no response.

block this number

same for me. fax beep , then tries again. Getting to stage where better to ignore and screen all incoming landline calls .

over 30 calls today every couple of minutes - just silence and beep like a fax - rang Telstra and they said to document time and duration of call and after 2 weeks they will send them a letter! - just got a another one!

3 calls within 15 mins. Seems to be a fax but hangs up after a few rings if not answered.

Surely thee is a way Telstra can block this number. 20 calls a day from a fax is bloody ridiculous and it is giving me the wally grits.....

Numerous calls from what seems to be a fax number

Midnight Calls

This number keeps calling (Fax and phone tones) with no voice or message - prank call? Why do they bother?
