With such technology, these devices can do voice communication with other people from the different parts of the world, with just the use of the internet. However, several mobile devices do not have VoIP yet and APIs for using this feature is not commonly available for developers. In connection with this, an Application Programming Interface (API) for mobile devices, that would enable further development of VoIP applications, or any other voice enabled applications, is necesssary. The proponents created such API for mobile devices, specifically Pal.
