You can block calls coming to a specific number from a specific number in your Press8 Control Panel. You can add as many blocks as you need.
*** Note: To update this feature, you must either "own" the number as a user or have Administrator priviledges. If you are not the Administrator or do not own the number that you want to set a block on, then please contact your Administrator to make these updates to your account.
Here are the instructions on how to do that:
Login to your Press8 control panel: https://manage.press8.com, then go to: Features=>Numbers. Click on the number that is being called,
and scroll down to the bottom area for "Caller Routes". Click "Add caller route",
and enter the 10 digit telephone number that is bothering you.
Then select the drop down for "Forward matching calls to:" and select a re-routed destination, such as:
1. "hang up", or
2. mailbox and then select the mailbox from the resulting dropdown.
2. Select mailboxes, and send the call to a mailbox.
Then click 'Save'.
