It's kinda hard to believe, but apparently Skype is completely sold out of Arizona phone numbers. I went to buy a Skype-In or Skype Online Phone Number on friday and the only choice it gave me was a Casa Grande areacode. I went back today and Arizona is completely missing from the State selection list. Hopefully they will get some new phone numbers at some point, either that or Arizona needs a new areacode. I had a Skype-In number a few years ago, but Skype didn't support outgoing caller-id which makes it kinda useless so I let it expire and didn't proceed with developing a version that works with Skype.
I'm working on a Skype version of Call On CRM now that the caller id issue is fixed and kinda need this to do development.
