Thanks for the replies. I wrote a script in SpiderMonkey to place a call, and upon connct turn on vmd, play a "press 1" prompt to see if there is a human, and then play some more prompts. If a voicemail beep is heard it starts playing a different prompt. I tested this with almost 300 phone numbers, but I suspect a disproportionate number of these are cell phones. Among the calls not answered by a human (nobody pressed 1), about 60% of the calls failed to recognize a beep. My cell phone is T-Mobile, and it doesn't detect the beep for it.

Hi, I have two issues I'd appreciate some help with.
A) I'm testing VMD and I'm getting a success rate of well under 50%. I know part of the reason is that some of the voicemail beeps it's encountering are very short in length (I've noticed this for T-Mobile and Sprint voicemails, and there may be others too), and it can't detect them. So my question is about the notes in the vmd section of the wiki which states, "The industry standard is 80% detection. This module if used properly should exceeds the standard by a very wide margin". I'm curious about whether I'm using it properly, and what I can do to make it work better. Thanks for the help.
B) When I place an outbound call and immediately play a prompt when the call is answered, the prompt sounds garbled to the person answering the phone. If I sleep for a second before playing the prompt, it sounds fine. Any idea of what would cause this?
Thanks, Adam
Adam,
Can I ask how you are "testing" vmd? Where? How?
