The Door bell function currently has 17 sounds avalible on it. Could you please please let us load our own wav files on either by including a brouse button or show me how to create my own "door bell.LIB" file as I two of my customer are not happy with the sounds on offer. I have already plenty of doorbell sounds just waiting to load on. If this is easy to do I would appreciate a quick fix as my two customers are reluctant to provide final payment over the little details such as this. (To be able to brouse for a custom set of voice phrases would also be very useful and make the Tica unit easier to sell)
