Android 2.3 (Gingerbread) and newer versionssupport a built in SIP/VoIP (Voice over IP) functionality. Thiswidget has two buttons: the left one gives you a shortcut to theSIP settings. The second one allows you to select how calls shouldbe routed primarily: you can select whether all calls should bemade via SIP by default, only Internet calls via SIP, or if youwant to be asked before each call.For Cyanogenmod-Devices, there's a quick settings tileavailable.For Android 5 (Lollipop) devices and newer:Google changed the SIP API, so the functionality has changed. Theleft button now redirects to call settings, it's one click fromthere to SIP settings. A direct link to SIP settings is currentlynot possible due to restrictions of Android 5, sorry. The rightbutton (and also the quick settings tile) now switches whether allcalls are made through SIP, or only ones going to a SIP address.Please set "Ask first" for "Make calls with" in "phone accountsettings", then this button will toggle between asking and makingcalls through cell phone network by default.Please note that by default the built in SIP functionality onAndroid only works via Wifi on most devices! Furthermore, some ROMsof network providers (branded phones) disable the SIPfunctionality. If you can't find SIP settings in your phone'ssettings, this widget probably won't work correctly.You can find the source code of this widget on GitHub:https://github.com/robert7k/sipswitch
