UBports is a community developed operating system for mobile devices. The project, which grew out of Canonical's abandoned Ubuntu Touch distribution, has announced that UBports users now have access to a voice-over-IP (VoIP) client in the operating system's app store. "Linphone has just landed in the Open Store. It's Ubuntu Touch's first VOIP (SIP) app. You can even use it to make regular telephone calls, too!" Further information on the Linphone app, such as features and known issues, can be found on the app's store page.
