I missed the call but the caller left a voice mail message. I listened to the voice mail and there were faint conversations in the background but the caller was silent and did not say anything.

Have had two calls from this number today. Missed the first, answered the second an they just hung up. Called back and it was an automated message from charitable organisation.. SCAM!!

I've had three missed calls from this number in 2 days, it's really annoying

yes I get calls from this number every day and getting fed up going to buy myself a whistle

Yeah its greenpeace, I get a call a day and they are diving me nuts!

These guys call me quite often, noone ever talks, there's a brief moment after I say hello then they hang up. Getting fed up with it

I believe it's someone calling on behalf of Greenpeace.

Im not sure but i keep getting calls from this person or what ever as well!! They call me like three times a day and i never pick it up in time because im always at uni.

Yeah I picked up a call and it instantly terminated. No idea. Nothing on google.
