Pages I need to investigate later on to improve my VoIP setup:
- https://www.callcentric.com/ Free SIP account (if needed)
- http://www.ipkall.com/ Get a free US phone number
- http://www.callwithus.com/ Seems to be a nice VoIP provider (with API etc)
I found these links after reading this Lifehacker article about using Google Voice outside of the US, which prompted me to think about my VoIP setup again (a project I'm thinking about for a long time already)
Next to that I want to find a cheap DID (Direct Inward Dialing) number in Colombia and in the Netherlands... The quest continues!
