Hello, I made a voicemail-box. If you press 1 it wil direct you to the voice-mail. Then I put my own company sound-file. "Leave your name or company bla bla bla" But then direct you hear. If this is correct press 1. The caller has no time the leave the message because after the tone it triggers a another menu. Can you customize the voicemail menu? And how van you change the duration of a voice-mail.
