I have an answering machine that is easier to use than Verizon voicemail, so I want to use that. But I'd like to have Verizon voicemail as the backup in case I'm on the phone when I get a call. I've just switched from Comcast, and I was able to do this. I've tried making Verizon's ring count 6 and my answering machine 5, but that didn't work - the Verizon voicemail still kicks in. Is there a way to do this? Thanks
