A. B. C. D. E.C.
To route a SIP call based on the value of the SIP INVITE Request-URI, the following configuration step needs to be performed:
D. Navigate to the local-policy configuration element and configure the to-address parameter to match the Request-URI value.
Explanation: When a SIP call is made, the Request-URI contains the destination address of the call. The Session Border Controller (SBC) can use the value of the Request-URI to route the call to the appropriate destination. To do this, the SBC can use a local policy to match the Request-URI with a specific address and then route the call accordingly.
The local policy configuration element is used to define policies for inbound and outbound SIP messages. The to-address parameter in the local policy configuration element specifies the destination address for the SIP message. Therefore, to route a SIP call based on the value of the SIP INVITE Request-URI, you need to configure the to-address parameter in the local-policy configuration element to match the Request-URI value.
Option A is incorrect because the from-address parameter is used to specify the source address for the SIP message, not the destination address. Option B is incorrect because the to-address parameter needs to match the Request-URI value, not the source address. Option C is incorrect because the from-address parameter is used to specify the source address for the SIP message, not the destination address. Option E is incorrect because the destination-address parameter is not used in the local-policy configuration element.
