Ok so yes you can use a VRS message as a greeting and then queue calls, check mem block 22-14. As for the scrambled messages, you simply have the wrong format for the audio file.. I use Audacity to convert files as it is free. load in your audio file, make sure the sample rate is correct and resample if necessary (all can be found on Google) then export the audio file (don't save it) and in the first step of exporting it, you can choose whether it is Alaw or Ulaw (I can never remember which is the right one so I export twice, one in each) then load the resulting file and check (if still wrong try the other).
