# Managing SIP rules
<a name="use-sip-rules"></a>

A SIP rule associates your SIP media application with a phone number or a Request URI hostname. You can associate a SIP rule with more than one SIP media application. Each application then runs only that rule. For an overview of how SIP rules work with SIP media applications, refer to [Understanding SIP applications and rules](understand-sip-data-models.md) in the previous section.

**Note**  
To create SIP rules, you need at least one DID or toll-free phone number with a **Product Type** set to **SIP Media Application Dial-In** in your Amazon Chime SDK inventory, or at least one Request URI hostname, the name assigned to an Amazon Chime SDK Voice Connector. For more information about phone numbers, see [Managing phone numbers](https://docs.aws.amazon.com/chime/latest/ag/phone-numbers.html). For more information about Request URI hostnames, follow the steps in the next section.
