My other cell phone was too simple. So I am submitting just the Dial Pad with Sound which is used for a simulation of a real cell phone by using Python coding or just for a simple BGE game or blender game engine. Just add your own back ground and your favorite cell phone 3d model then press P for play. Place the mouse over the number and right click for the sound/animation. The button number will indent. Other button can be used for a contact data base or actual stream two way audio. Make sure you sound card is working with blender by adding your own sound test file which you build yourself and/or turn up your volume.
