Ask Slashdot: Data-Only Phone, Voice Over WiFi?

enFi writes "I want to pay one ISP (only!) for data (only!), and use it for my smartphone and my computer; and until they catch up, I want not to inconvenience the rest of the world — still let them call a phone number.

I could just use Skype and an Online Number, but talk of Sipdroid+pbxes.org+GV and the recent Google Voice / SIP article make me think I'm only starting to untangle the mess of services and options. Is there a good (not to mention best) way to do this?"

My co-workers and I have tried paid alternatives to GV, such as phone.com. The latency issue is similar, though voice quality and consistency is somewhat better.

The disadvantage is, of course, that you have multiple phone numbers and it's sometimes confusing for people who are used to you calling from one number.

My suggestion, if you're going to do 4G wireless is to just use a VOIP carrier like Callcentric with your data plan. However, I have doubts that the latency and reliability will be adequate.

I set asterisk up to route local calls and 800 calls out the landline (Which was usually clearer and had less echo) and send all others to my voip provider. I also set it up so that inbound calls from priority people were routed to my cell phone number if my cell phone sip device was not registered on the local wlan. This just took the call from the land line and dialed my cell phone number through voip. That way no one ever got to know my actual cell phone number.

    If you have a static IP on the open internet, you can establish a sip connection to asterisk from anywhere you have a wireless network connection. YMMV, and that's a lot of crap to expose to the internet.
