An administrator is configuring a secure SIP trunk on Cisco UCM. Which value is required in the Secure Certificate Subject or Subject Alternate Name field to complete this configuration?

  • A the common name of the remote device certificates
  • B the fully qualified domain name of all Cisco UCM nodes that run the CallManager service
  • C the common name of the Cisco UCM CallManager certificate
  • D the fully qualified domain name of the remote device that is configured on the SIP trunk
Explanation

For TLS device authentication, Cisco UCM validates the subject or subject alternative name from the remote SIP trunk device’s TLS certificate. Cisco’s secure SIP configuration guidance specifically requires this field to match the remote device certificate’s Common Name (CN).
