is there a way of filtering a voicemail message?
for instance someone call and connected to voicemail, IVR said that “say the message after the tone”, but after the tone the caller say nothing and after a couple of minute the call is bing hangup. so obviously the Asterisk server will consider it as voicemail and by the time the owner of that extensions access the mailbox he/she will be informed for new message and as he/she open it its only “hiss” as in nothing.
so i would like to remove or not to save this message in the mailbox
how its gonna be?
