I've been looking around on google for a bit but I can't get around call center call routing. Which is if someone calls my tech support line at 5:00 pm it will go here vs if they call at 5:00 am, which is cool unto itself. My question is if I normally live in Oregon and I suddenly fly to New Zealand, then my friend calls my phone number how does the cell network know what paths to take and where to transmit the call from? I was thinking about this and I have an idea but I don't know if it's right. My idea was as soon as I were to land in the Kiwi nation my phone would ping a cell tower and basically say here I am. Then my phone's ID would be passed into some sort of international list that is 7.3 billion numbers long. Which thinking on it wouldn't actually be a huge amount of data. Then the network would have a pre selected route and use a travelling salesman type problem to get my call to me. Is this about right? Also makes me wonder when I type in www.electronicspoint.com how does my computer know which other computer to talk to? Probably something similar? Does this process have a name?
Thanks for any info, I find this stuff fascinating.
