The dial-peer command with the lowest preference will be matched first, followed by the next lowest preference and so on until a matching dial-peer is found.
Out of the given options, the dial-peer command with the lowest preference for inbound SIP dial-peer matching is option C, Destination-pattern <number-string>. This command is used to specify the called number pattern to match for inbound calls on this dial-peer.
The other options are as follows:
A. Incoming URI to <uri-tag>: This command is used to match inbound calls based on the Uniform Resource Identifier (URI) tag. It has a higher preference than the destination-pattern command.
B. Incoming called-number <number-string>: This command is used to match inbound calls based on the called number. It has a higher preference than the destination-pattern command.
D. Incoming called-number e164-pattern-map <pattern-map-no>: This command is used to match inbound calls based on the E.164 pattern map. It has a higher preference than the destination-pattern command.
E. Answer-address <number-string>: This command is used to specify the address to which a call is answered. It does not affect inbound dial-peer matching.
In summary, the dial-peer command with the lowest preference for inbound SIP dial-peer matching is the destination-pattern command, option C.
