This is possibly just used as a routing number from foreign calls. I get calls from this number too, but only when my friends/family call from other countries. (Long story short: pretty much when foreign calls are routed into the US, it's more cost effective for companies to "route" the signals to local phone numbers, and ultimately, to your phone)
yeah this is definitley something to do with intl calls, today a friend sent me a link to -jaxtr- some internet phone service, and i immediatley got the call from that number.
its a 3rd party phone nr.....
