Same here. It also allows me to give out a US address to those who can't process international numbers. A surprisingly large number of very large businesses can't process an international number (for one, nobody in the IRS not in the International Department can call international, for another, Wells Fargo can send me international mail, but also can't call international) - or so say the people I've spoken with in such organizations. It could be training, rather than technical/financial, but most companies lock down international dialing for fear of scams. There are still constant reports of PBX exploits generating $100,000+ phone bills to a 900 number equivalent outside the US.
The problem with Voice is that I signed up in the US, so I get free calls. But those that don't sign up until they are outside the US will not get that treatment, unless they sign up from within the US, and Google has taken to identifying IPs based on usage, not GeoIP, so you could use a VPN service with a US ARIN address physically located in Texas and Google will still consider you as being in Europe. The only "reliable" away is to have someone in the US sign up for you, then send you the login.
