I need help creating a vm-intro.ulaw file with nothing in it. This will take out the default message:
vm-intro: Please leave your message after the tone. When done hang up or press the pound key. (simple tone sound plays)
I used this command in sox:
sox -V vm-intro.wav -r 8000 -c 1 -t ul vm-intro.ulaw
It did not work. When the call goes into voicemail my personal message plays and then the call drops.
My quick fix was to rename the beep.ulaw file into vm-intro.ulaw but it is annoying to hear the beep twice before leaving a message.
