Block Phone Numbers
With the Stratus v42 update, you can use the Block 
icon and the Blocked Numbers menu on the Call History page to block phone numbers from calling you. Use the module below to explore the different ways you can block numbers from the Call History page.
Note: If you are an Office Manager blocking phone numbers using the Domain Call History page in the admin version of the Stratus web portal, these phone numbers would be blocked for your whole organization.
Block a Recent Caller
If you have recently spoken to someone that you need to block, you can block their phone number using the Block icon found on their call log.
1. Filter and scroll to find the call you had with the person that needs to be blocked and click the Block icon.
2. On the confirmation message, click the Yes button.
✔ You should now see a Block number icon next to the phone number in your Call History.
For any future calls you receive from the blocked number, the call will automatically be rejected, and a Blocked tag will appear in the Duration column for that call.
Block Multiple Numbers
With the Stratus v42 update, there is now a new Blocked Numbers tool that can be used to block malicious phone numbers.
1. Click the Blocked Numbers button. 
2. In the Blocked Numbers menu, type the phone number that needs to be blocked. 
3. Click the Add button to add this phone number to your Blocked Numbers list. 
✔ You should see a confirmation message that the phone number was added to the list.
You should also see the phone number listed alongside any other blocked numbers. 
4. Repeat steps 2 and 3 for additional phone numbers that need to be blocked.
✔ Now if you receive any calls from the phone numbers you have blocked, the calls will automatically be rejected, and a Blocked tag will appear in the Duration column for those calls.
Import a Spreadsheet
If you have a list of phone numbers that should be blocked, you can download and fill in a spreadsheet of those numbers. This spreadsheet can be imported so that the list of phone numbers gets added all at once.
1. Click the Blocked Numbers button.
2. In the Blocked Numbers menu, click the Import button. 
3. In the Import From File menu, click the Download Template button. 
✔ You should see a .CSV spreadsheet download through your browser.
4. Open the downloaded template spreadsheet.
5. Type a phone number into the cells of column A.
6. When you have typed in your phone numbers, save the spreadsheet by pressing CTRL + S or clicking the Save icon.
7. Back in the Import From File menu, click the Browse button and select the updated template.
8. Click the Upload button. 
✔ You should see a confirmation message that tells you how many blocked phone numbers were imported. It will also state if any of the phone numbers were duplicates.
You should also see the phone numbers from the spreadsheet listed in the Blocked Numbers menu.
Now if you receive any calls from the phone numbers you have blocked, the calls will automatically be rejected, and a Blocked tag will appear in the Duration column for those calls
Unblock a Phone Number
If you have added a phone number to your Call History's Blocked Number list, you can remove it at any time. Removing a phone number from the Blocked Number list will unblock that caller so that you can start receiving calls from that phone number again.
To unblock a blocked number…
- On the Call History page, click the Blocked Numbers button.
- In the Blocked Numbers menu, click the Delete icon next to the phone number that needs to be unblocked.
Quick Tip: Alternatively, you can click the Unblock
icon next to the log of a recently received call from a blocked phone number. 
✔ You should see a confirmation message that the phone number has been removed from the Blocked Numbers list.
- Repeat step 2 for each phone number that needs to be unblocked.
