Who called from 2504123301

GOt a call to a fax line from this number.  No fax came through.

just called me but didn't respond to my "Hello" so I hung up.  I have the TeleZapper so maybe they had already been cut-off by the time I said Hello

Just had a call from recorded lady's voice, based in QUE, doing a short survey.  I hung up after a few seconds.  This was on my unlisted cell phone too.

Just received a call, it was a woman speaking what sounded like Chinese.  After trying to figure out what she was saying I said "Sorry I only speak English" and she said "sorry" and hung up.

I called this number back and got a dial tone. Must be VOIP or something similar.
