Refer to the exhibit. An engineer is working on a ticket that reports TEL1 cannot call TEL2.
These dial peers are configured to route the call between the endpoints.

While troubleshooting, the engineer discovers that the Cisco Unified Border Element is giving the error "SIP/2.0 403 Forbidden".
Which two Cisco Unified Border Element configurations resolve this issue? (Choose two.)
A. voice service voip mode border-element ip address trusted list ipv4 10.1.1.0 255.255.255.0 ipv4 10.2.1.0 255.255.255.0 allow-connections sip to sip sip bind control source-interface loopback0 bind media source-interface loopback0
B. voice service voip no ip address trusted authenticate mode border-element allow-connections sip to sip sip bind control source-interface loopback0 bind media source-interface loopback0
C. voice service voip mode border-element ip address trusted list allow-connections sip to sip sip bind control source-interface loopback0 bind media source-interface loopback0
D. voice service voip mode border-element allow-connections sip to sip sip bind control source-interface loopback0 bind media source-interface loopback0
E. voice service voip mode border-element ip address trusted list ipv4 10.1.1.0 255.255 255.0 ipv4 10.3.1.0 255.255.255.0 allow-connections sip to sip sip bind control source-interface loopback0 bind media source-interface loopback0
I agree
Yes both options are correct :
so, if the question ask for two configurations choose : B & E.
Better view of the answers, I believe its either of the answer will fix the issue and not both of them together.
B
voice service voip
no ip address trusted authenticate
mode border-element
allow-connections sip to sip sip
bind control source-interface loopback0
bind media source-interface loopback0
E
voice service voip
mode border-element
ip address trusted list
ipv4 10.1.1.0 255.255 255.0
ipv4 10.3.1.0 255.255.255.0
allow-connections sip to sip
sip bind control source-interface loopback0
bind media source-interface loopback0
You are right
