This is the number that Skype "on the go" uses for local exchange. It keeps caller info anonymous but with right computer forensic skills & tools (and a search warrant from your local judge ;-) you could locate caller's IP address. Also this exchange number can be traced to telecom company which could provide more detailed account of the connection...

I got a call from this number but I can't get through when I call back.
