This document discusses about the issue which occurs while trying to upload CUE AA custom greeting and the steps to troubleshoot this issue.
With Cisco Unity Express Autoattendant, uploading the custom greeting file fails with the error message "Unsupported Audio Format".
When recording the file which is to be uploaded as the custom greeting, make sure that these conditions are met:
The file should be set up as a .wav format and it cannot be larger than 1 MB. Record the greeting using a valid recorder in .wav format.
In addition, the file needs the following parameters to function properly with the system (you can check this on the file properties)
Audio Sample Size
Audio Sample Rate
For Rel2 in addition to the above mentioned, there is an application called Greeting Management System using which prompts can be recorded. These prompts
once recorded are saved on the disk as user prompts (example: Userprompt01929020.wav).Using GUI, Administrator should be able to download these prompts, rename them asneeded and upload back to CUE.
Make sure that there is no silence in the end of the prompt. If the scripts are written in such a way that the prompts are not interruptible, the user hearing the
prompts would not know if the system stopped playing the prompt or not (system could be playing the silence part of the prompt'). For example, CUE allows AAwelcome.wav used in the default Auto Attendant script to be replaced by custom prompt. Default AA script is written in such a way that prompt is uninterruptible. Any DTMF entered during the prompt being played will not interrupt the prompt.
