No voice on incoming calls.

So in Features there is a drop-down whose options are:
Allow Blocked Calls
Block Calls Marked as Private
Block All Unknown Calls


What is the difference between the last two? Currently I have "Block Calls Marked as Private" but if I set it to "Block All Unknown Calls" I should be okay and not run into the problem with callers not hearing us or the answering machine not playing its message?


Thanks!

Block Calls Marked as Private blocks only those callers where the CID display shows up as Private which means there will also be no number displayed on the CID.

Block All Unknown Calls is similar to Block Calls Marked as Private but does not stop at just Private, it will block Anonymous, Unknown, Restricted or any call with a blocked number.
