Refer to the exhibit.

You have received a trouble ticket stating that calls to local PSTN numbers
are failing. To place a call, Cisco Unified CallManager users dial the access code “9,” followed by
seven digits. After entering the debug voice dialpeer command on the H.323 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 call is not matching an inbound dial peer resulting in a codec mismatch.

B.
Cisco Unified CallManager is stripping the access code, resulting in only seven digits being
sent to the gateway.

C.
There is a physical layer issue with the circuit.

D.
The gateway dial peer needs to prefix the access code to the called number.
