I called the number back and got a message stating it is for a 'line' rental and funding for heart research. I opted out by typing in my number as requested.

Unity 4 calling on behalf of Medicines San Frontiere. looking to update my regular contribution.

Three calls from this number over past week at about 5 to 6pm. Have not answered once as I do not recognise the number as a 'friend' and it is from a different State (I am in WA).

Second time for this number (02) 8020 3515 rings ,when you pick up there's no one there then it disconnects ,so it is now being added to my DNA ( do not answer ) list of contacts which is growing every week .assuming it is one of those calls that log the number of times it is answered and the actual time it is answered .

Caller: Medicins Sans Frontier

These guys try using mulitple different numbers. I block them all and the next one that gets through, I'm going to cancel my quite substantial contribution. I find their guilt-creating tactics deplorable. They take a sizeable % for this fund-raising.

Caller: Unknown

Same as everyone else, calls at least once a day. I don't answer and they never leave a message so they are now blocked!

I have had calls from this number everyday, sometimes twice or three times. I have never answered and will not! Dodgy as!!

how do you block it?

This number tries at least once a day, sometimes twice. Never leaves a msg, tonight was nearly 8pm on a Friday plus earlier today too. My msg bank states my line is used for internet only and don't bother calling again but they're persistant.

Caller hung up when call was answered.

every day for last couple of weeks. Either 2pm or 5.30pm. Never anyone there if I answer. Onto the Block list.

Have a couple of calls from this number over the last few days and when we answer they hang up. Not appreciated as I have a disability and it takes me a while to get to the phone to answer.
