Ask HN: Changing VoIP Providers

My long-time ISP and VOIP provider is turning off my DSL circuit next month, and I've been in the process of migrating to a new ISP and need a new VOIP provider. There is a vast array of VOIP providers with many different service plans, features and pricing structures. Since this isn't an area where I'm an SME, I've searched around quite a bit, but am a little overwhelmed by the number and type of services available. At a minimum, I need to be able to make and answer actual phone calls with my existing VOIP number and forward incoming calls to my (also existing) mobile number. The various "standard" features: 1. Call forwarding after $X rings 2. Access/use via mobile device 3. Inbound/outbound international (I'm in the US) calls (both when I'm in the US and outside of it. Those would be useful, but all I really need is call forwarding and calling worldwide from inside the US. It would also be useful to be able to manage my own VOIP-enabled desk/cordless phone (perhaps through something like Asterisk[0]), but that's not strictly necessary. Ideally, it would be great if it were free, but that's not strictly necessary either. I started looking at Google Voice (which doesn't provide all the features listed above, but as I said, I only need inbound/outbound calling and call-forwarding). That said, I try to stay as far away from Google as possible whenever I can. What sorts of experience have other folks had with various VOIP providers? What sorts of provider/feature recommendations would you make toward enhancing privacy and security for VOIP services? [0] https://www.asterisk.org/ Edit: Added the missing link.
