You'll need to file a jira.  Include a script that exhibits the behavior.  You'll also need to document it fully and the dialplan entry you're using to produce this issue.

Hi Michael,

the cell phone carriers in the US use a beep tone that is out of the range that is typically detected. i've had success using tone_detect rather than mod_vmd. if my memory serves me correctly 786 is the tone you need to listen for. the same is true for sprint and t-mobile voice mail beeps
