Who called from 2124445000

I received two calls within one minute on Sunday 17.02.2008, but no answer from other side of the line.

I got a call from this number on 4/15/08 and twice today 4/18/08 and they left a voicemail and in the voicemail you can hear the other side trying to do something

Got 2 calls from this number. One after midnight and one early the next morning. sounds like an automated call, silence then it disconnects

they called me this morning said nothing i hung up

This is a phone card number, It just means someone was calling you through a phone card most likely from overseas and sometimes the call doesnt connect properly
