Question

• CDestination Port in SIP Information section of the SIP Trunk configuration
• DIncoming Port in SIP Trunk Security Profile configuration
• EDestination Port in SIP Trunk Security Profile configuration

• B
  16% (7)
• C
  71% (32)
• E
  4% (2)

Explanation

Two separate settings control the port used for SIP trunk traffic. Option C (Destination Port in the SIP Information section of the SIP Trunk configuration) controls the outbound port - the port to which CUCM sends SIP signaling toward the provider. Option D (Incoming Port in the SIP Trunk Security Profile) controls the inbound port - the port on which CUCM listens for SIP signaling from the provider. Together, these two settings ensure port 5065 is used for both directions. Option A is incorrect because there is no 'Incoming Port' field in the SIP Information section of the trunk config. Option B is incorrect because the SIP Profile does not contain an incoming port setting. Option E is incorrect because the destination port belongs to the SIP Trunk config, not the Security Profile.
