Explanation

Cisco IOS evaluates incoming SIP dial peers in a defined order of preference. The 'incoming uri' command has the highest matching priority. If a dial peer has an 'incoming uri' configured and it matches the SIP Request-URI or From header, that dial peer is selected before any other criteria are evaluated. The order after that is: answer-address, then incoming called-number, and finally destination-pattern (as a fallback). Because URI-based matching is the most specific and flexible mechanism in SIP, Cisco places it first in the evaluation sequence.
