A user forwards a corporate number to an international number. What are two methods to prevent this forwarded call? (Choose two.)
A. Set the Call Classification to OnNet for the international route pattern.
B. Block international dial patterns in the SIP trunk CSS.
C. Configure a Forced Authorization Code on the international route pattern.
D. Set Call Forward All CSS to restrict international dial patterns.
E. Check Route Next Hop By Calling Party Number on the international route pattern.
B is not correct as the forwarding party is the user device (using line’s call forward CSS) and not the SIP trunk. Therefore the right answers are C and D.
