Refer to the exhibit. You have received a trouble ticket stating that calls to international numbers are failing. To place an international call, users dial the access code “9,” followed by “011,” the country code, and the destination number. After entering the debug isdn q931 command on the MGCP gateway, you have the user attempt the call again.
Based on the debug output, what is the most likely cause of this problem?
A. Cisco Unified CallManager is not stripping the access code before sending the call to the gateway.
B. The gateway dial peer needs to prefix “011” to the called number so the PSTN knows this is an international call.
C. The user’s CSS does not permit international calls.
D. The TON is incorrect.
E. The circuit is not configured correctly or has a physical layer issue.
