We can't do this as a customization in our app, but it's possible!The phone call from black listed phone number are filtered (no ring) but they can let voice message on the voicemail.
How to forbid the access to the voicemail to th black listed phone number ?
Despite this issue I am happy with this app.
Thank you for your support.
Will those who are not blacklisted be able to leave voicemails?
My service provider does not allow turning off 'call forwarding to voicemail on busy event' so I set it to forward to one of the blacklisted numbers. When I receive a call from that number it is just a computer call. 'Call waiting' is enabled. Do you think that will work?
I have 'Block all except contacts" selected on. It seems to me that in accordance with your instructions above, a blocked number (never a contact number) should get a busy signal and not be sent to voicemail. A blacklisted number should get a busy signal and get sent to voicemail. So it appears that I should never add numbers to my personal blacklist if I never want to see anything about them. I should only block them. Have I got that correct?
