Call Block

Keep unwanted calls away from the business numbers and extensions your team uses for customer enquiries.

In the CRM: Voice Features → Phone System → Applications → Call Block

Keep the team focused on useful conversations

Call Block lets you set rules for unwanted calls. Choose whether a rule applies to inbound or outbound calls, which extension it affects and what the phone system should do when the rule matches.

For a business running advertising, this can help staff spend more time on customer enquiries when the same unwanted number keeps calling.

The native rule form. Review the number and extension before saving a rule. Select the image to enlarge it.

Add a blocking rule

  1. Open Voice Features → Phone System → Applications → Call Block and choose Add.
  2. Select Direction: Inbound for calls arriving at the business, or Outbound for calls made from it.
  3. Choose the affected Extension, or All when the rule is meant to apply across the available extensions.
  4. Enter the Country Code and Number. Use Caller ID Name when a name is part of the rule you intend to configure.
  5. Choose the Action, such as Reject or Busy, or an offered destination that fits the intended handling.
  6. Keep Enabled on, enter a Description explaining the reason and choose Save.

Use a recent call to identify the number

The add screen also shows Recent Calls. Review the caller, number, destination and date so you can identify the call you mean. Select the intended entry and use Block to review the blocking action.

Check the direction and extension selection before confirming. A useful description, such as “Repeated unwanted calls to sales”, helps the team understand the saved rule later.

Review and maintain the rules

The list shows the direction, extension, caller information, Count, Action, Enabled, date added and description. Search for a rule and open it when the handling needs to change.

Use Enabled to control whether a saved rule is active. Review the selected rows and the confirmation when removing rules.

Keep call handling aligned with your customer process: legitimate enquiries should continue to reach the assigned staff, buyer destination or configured AI agent.
