Recently CyanogenMod has updated its OS from new Google code recently released. This code supports the native SIP stack which enables people to make calls through wifi or through their data connections. This method is the best solution because of it’s simplicity and secondly, it has the best call quality of any thing out there. Example: sipdroid, groovIP, SIPsimple, viber, etc. So basically what people can do is make and receive calls through their Wi-Fi or through their 3G/4G data connection. This is a perfect solution for people that have little to no coverage in their homes. I have a very professional video that shows users, even “newbs”, how to get it set up.
