Mongoose Metrics undergoes a rigorous process in blocking and identifying spam calls across campaigns and accounts. All phone numbers undergo a rest period before and after Mongoose Metrics acquire them into our pool of numbers. After a toll free number is assigned to a campaign, an algorithm determines whether the call is from a spammer based on the frequency and length of calls. Once a number is identified as a spammer, it will be prompted during a call to "press 1 to continue" to filter out automated messages.
Mongoose Metrics allows customers to block phone numbers on campaigns in the case of a bad number. To block a phone number from all campaigns at the account level, access the following article: https://support.mongooseportal.com/entries/26056573-How-to-Block-a-Caller-from-an-Account
To block a phone number at the campaign level:
Enter your email address and assigned password into the appropriate fields and click "Login"
Click on the tab labeled "Campaign".
Click on the tab "Edit Campaign" next to the campaign that needs a number blocked.
Click on the Campaign Options header on the left and select "Configure Call Block Filter" from the drop down.
There are three options for Call Blocking Filters: block a specific area code or number, block all calls from within the US, or block any calls from a toll free number. Once a call blocking filter has been added to a campaign, any logged call attempts from a blocked number are stored on this page to monitor.
