An engineer has temporarily disabled toll fraud prevention for SIP line calls on a Cisco CME12.6x and must enforce security and toll fraud prevention for the SIP line side on Cisco Unified CME. Which configuration must be used to start this process?
A.
voice service voip enable ip address trust list
B.
voice service voip ip address trusted list
C.
voice service voip ip address trusted authenticate
D.
voice service voip enable ip address trust authentication
Unified CME 12.6 or a later version for SIP line calls.
Unified CME 8.1 or a later version for secure trunk calls.
SUMMARY STEPS
enable
configure terminal
voice service voip
ip address trusted authenticate
ip-address trusted call-block cause code
end
show ip address trusted list
The answer is C. The command to disable is "no ip address trusted authenticate" under voice service voip config. To enable you would use "ip address trusted authenticate" under voice service voip config.
If you simply type "ip address trusted list" you get put in to that sub-config mode and do not re-enable it.
"In Unified CME, IP address trusted authentication is enabled by default. When IP address trusted authenticate is enabled, Unified CME accepts incoming VoIP (SIP/H.323) calls only if the remote IP address of an incoming VoIP call is successfully validated from the system IP address trusted list ."
So, Answer is B, as you only need to start with these commands
Configure IP Address Trusted Authentication for Incoming VoIP Calls.
SUMMARY STEPS
1. enable
2. configure terminal
3. voice service voip
4. ip address trusted authenticate
5. ip-address trusted call-block cause code
6. end

My only thought is in Unified CME IP address trusted authentication is enabled by default.
so to start the process is B.
voice service voip
ip address trusted list
