# Unassigning Voice Connector phone numbers
<a name="unassign-numbers"></a>

The following procedures explain how to unassign phone numbers from Amazon Chime SDK Voice Connectors and Voice Connector groups. You can't unassign phone numbers used by SIP media applications. Instead, you delete the SIP rule. For more information about deleting SIP rules, refer to [Deleting a SIP rule](delete-sip-rule.md) in this guide.

**Note**  
Unassigning numbers and deleting SIP rules disables the users' telephony capabilities. However, unassigned numbers remain available in your inventory, and you will be billed according to their product type.
