This number has called me twice in two days. I called back on my unlisted landline and a recorded voice said something like "Hello you've called Waysign (or something similar sounding) and we call on behalf of charities..." I do hope they don't start really pestering me...

This number Called me several times. They left a voicemail without a message and just breathing at the end

I called back number (02) 9199 9394 reached voice mail for a charity company but did not say the name.

Rang once and disconnected. Pretty suss. I blocked the number based on comments above.

Caller: Unsure

They left a message with heavy breathing and a laugh at the end. No name, but was this number.
