Set Up VoIP Calling on Android 2.3 Gingerbread [Video]

SIP voice-over-internet calling is one of the quiet new features of Android 2.3 a.k.a. "Gingerbread". Without any third-party apps, you can set up any SIP-compatible phone service to make calls over your data network. This video shows the steps, and now we're intrigued as to whether a free SIP client, like the SIPGate we used in our Google Voice setup, works in Android as well. We'll try it out, but have you already given it a go? Tell us in the comments. [via Android and Me]
