Deleting voicemail from hang-up
Is there a way to write a rule or something that will automatically delete hang-up voicemails? Some of the spam calls that come in actually get to VM somehow and then leave a 7-10 second VM with nothing on them. Of course, I have to go through the process of deleting those to get to any real VM. I would prefer to set a rule, if possible, to get rid of these.
