Managing SIP rules
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 in the previous section.
Note
To create SIP rules, you need private phone numbers or at least one Request URI hostname. For more information about phone numbers, see Managing phone numbers. For more information about Request URI hostnames, follow the steps in the next section.
