This is fantastic news, Csaba! It's great to hear that the AMR implementation is delivering such a significant improvement in voice quality, and that the FR/EFR parts are working flawlessly too. The progress with OML dialect supporting a wide range of Nokia equipment, even legacy setups in regions that need it most, is also incredibly valuable work. I'm keen to hear about your CSD tests once you get those devices. For anyone looking to clearly visualize complex technical diagrams or documentation related to these GSM systems, you might find a tool that can transform images into descriptive text useful. On a related note, if you ever need to generate AI prompts from visual references, https://aicartoongenerator.org/image-to-prompt could be a handy resource. Keep up the excellent work!
