Block spam numbers

Omnichannel for Customer Service offers a suite of capabilities that extend the power of Dynamics 365 Customer Service Enterprise to enable organizations to instantly connect and engage with their customers across digital messaging channels. An additional license is required to access Omnichannel for Customer Service. For more information, see the Dynamics 365 Customer Service pricing overview and Dynamics 365 Customer Service pricing plan pages.

In Omnichannel for Customer Service, as an administrator, you can block spam phone calls that your agents receive as part of their incoming customer calls. By blocking spam calls, you can help improve efficiency and productivity of agents and prevent long wait times for actual customers who are in the queues. Your agents and supervisors can also flag off incoming calls as spam, that you can later review and block as spam.

Review phone numbers marked as spam

You can review phone numbers marked as spam in the Customer Service admin center or Omnichannel admin center (deprecated) app.

  1. Go to one of the apps, and perform the following steps.

    1. In the site map, select Customer Settings in Customer support. The Customer settings page appears.
    2. In the Blocked numbers section, select Manage.

    The Blocked numbers page is displayed.

  2. In the Blocked numbers section, you can do the following:

    • Pending review tab - Shows the list of numbers that have been flagged as spam by your agents and supervisors. You can view the report for each phone number, and then block the specific number as spam. Select any number from the Pending review list, and then you can do the following:

      • Block - Select to block the number; the agent will no longer receive any calls from the blocked number.
      • Remove from list - Select to remove the number from the Pending review numbers list and clear the number from the spam numbers list.
      • View report history - Select to view the reports for the specific phone number in the Pending review list. You can review all spam notification reports by viewing the report history​. You can visit the conversation history page to review the conversation or recordings.​ You can also choose to either block the number or remove the number from the pending review list.
    • Blocked tab - Shows the list of phone numbers that have been blocked as spam.

Manually block phone numbers

  1. Navigate to Blocked numbers and select Manage.

  2. Select Block a number.

  3. In the Block a phone number dialog, enter a phone number, add any comments if you'd like, and then select Block this number.

Automatically block phone numbers

You can set conditions so that some numbers are automatically added to the blocked numbers list if they match certain conditions based on the number of reports. Using the Auto-block option, you can also automatically block numbers if they're reported as spam, say two or more times. This not only saves time in reviewing every blocked call report received from your agents, but also helps remove any delay from your end when you have too many spam numbers to review. The auto-block option is also useful in situations or instances where there might be a surge in spam calls from different numbers.

  1. Navigate to Blocked numbers, and select Manage.

  2. In the Auto-block section, select Set up.

  3. In the Auto-block dialog that appears, do the following:

    1. Enable the Turn on auto block toggle.
    2. Enter a value for the number of reports in the Block reported phone numbers if they receive field. For example, if you entered 2, then the phone number would automatically get blocked as spam after two reports are received.
  4. Select Save and close.
