Refer to the exhibit. Which SIP trunk security profile configuration on the Cisco UCM server is used for a secured SIP trunk to an Expressway server that is already integrated with the Cisco UCM for Mobile and Remote Access?
A.
Device Security Mode: Encrypted -
Incoming Transport Type: TLS -
Outgoing Transport Type: TLS - Incoming Port*: 5061
B.
Device Security Mode: Encrypted -
Incoming Transport Type: TLS -
Outgoing Transport Type: TLS - Incoming Port*: 6061
C.
Device Security Mode: Non-Secure Incoming Transport Type: TCP+UDP
Outgoing Transport Type: TCP - Incoming Port*: 5060
D.
Device Security Mode: Authenticated
Incoming Transport Type: TLS -
Outgoing Transport Type: TLS - Incoming Port*: 6061
A and C are wrong, per the MRA deployment guide you should "configure the Incoming Port to be different from the Line ports", the line ports being 5060 and 5061.
That leaves B and D. B is the better option because it has Device Security Mode set to Encrypted which secures the media.
