The integration also means that incoming calls are shown in a similar way to incoming cellular call (i.e. showing the standard incoming call screen / notification). Nimbuzz describe the calls as being "HD quality". This is related to the codec used for encoding the audio and means that call quality should be better than standard cellular voice calls.
To go along side the new voice calling feature, Nimbuzz has also added calls logs, allowing you to easily view the calls and voicemails made, or receieved, using the app. There are also a small number of bug fixes and minor improvements that sould improved the stability of the app.
