Paul: Is there a phone-specific transcoding layer in Mbuni so far? The idea is that the MMSC has a "receiver-confirm" push layer that acts as filter while the receiver asks for the MMS. By this approach you can assure that specific phones that don't support GIF image will get a PNG or JPEG, and same can be performed for audio formats in general. It's always better to reduce the quality drastically, ie. by converting from mp3 11KHz mono to analog phone quality, then to refuse to deliver the content in general.
Yes this layer exists (it is called "content adaptation") and is the one calling mpg123 and so on. What happens is that mbuni is converting the message, then realising that the resulting message is too large for the phone, and dropping it.
