DRAG DROP
Click the matching criteria for inbound POTS call on the left and drag them to the order of selection on the right.

Answer:

Explanation:

The router or gateway matches these items in this order:
1. Called number (DNIS) with the incoming called-number command. First, the router or
gateway attempts to match the called number of the call setup request with the configured
incoming called-number of each dial peer. Because call setups always include DNIS
information, it is recommended to use the incoming callednumber command for inbound dial
peer matching
2. Calling Number (ANI) with the answer-address command If no match is found in step 1, the
router or gateway attempts to match the calling number of the call setup request with the answeraddress of each dial peer. This attribute can be useful in situations where you want to match calls
based on the calling number (originating)
3. Calling Number (ANI) with the destination-pattern command If no match is found in step 2,
the router or gateway attempts to match the calling number of the call setup request to the
destination-pattern of each dial peer. For more information about this, see the first bullet in the
Dial Peer Additional Information section of this document.
4. Originating Voice-port (associated with the incoming call setup request) with configured dial
peer port ( applicable for inbound POTS call legs) If no match is found in the step 3, the router or
gateway attempts to match the configured dial peer port to the voice-port associated with the
incoming call. If multiple dial peers have the same port configured, the dial peer first added in the
configuration is matched.
5. If no match is found in the first four steps, then the default dial peer 0 (pid:0)command is used.
