Which statement best describes dial peers in voice gateway?

• A.Dial peers are configured with call legs that are essential to implementing dial plans and providing voice services over an IP packet network.
• B.Dial peers are call legs that are used to identity call source and destination endpoints and to define the characteristics that are applied to each call leg in the call connection.
• C.Dial peers create physical connections called call legs to complete an end-to-end call.
• D.dial peer is a physical addressable endpoint in a voice gateway.

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.The gateway dial peer needs to prefix "011" to the called number so the PSTN knows this is an international call.
• B.The TON is incorrect.
• C.Cisco Unified CallManager is not stripping the access code before sending the call to the gateway.
• D.The circuit is not configured correctly or has a physical layer issue.
• E.The user's CSS does not permit international calls.

You have received a trouble ticket stating that the MWI light is not coming on for a group of users. Further investigation reveals that the affected users are connected to the same subscriber in the cluster. Users that are connected to other subscribers in the same cluster are not experiencing this issue.
What is causing this problem?

• A.The MWI numbers for this subscriber have been changed.
• B.Database replication has an error or has failed.
• C.The voice-mail ports assigned to the subscriber are down.
• D.The Cisco Unity voice-mail services need to be restarted for the subscriber so all the users will receive proper MWI message indication.
