Question #3
An administrator is troubleshooting call failures on an H.323 gateway via the CLI. To see signaling for media and call setup, which debug must the Administrator turn on?
Correct answer: B
Explanation
H.225 carries call setup signaling and the embedded H.245 media negotiation, and debug h225 asn1 decodes those ASN.1 encoded messages, showing both call setup and media capability exchange on the H.323 gateway.
Question #5
Which section under the Real-Time Monitoring Tool allows for reviewing the call flow and signaling for a SIP call in real time?
Correct answer: C
Explanation
RTMT's Voice/Video > Session Trace Log View > Real Time Data collects the SIP signaling of a call as it happens and draws the call flow ladder diagram; Open From Local Disk only replays previously downloaded logs.
