When troubleshooting call failures on an H.323 gateway via the CLI, an administrator may need to turn on debugging to see signaling for media and call setup. In order to do so, the administrator must turn on the appropriate debug command.
The correct debug command to turn on in this case would be "debug H.323 messages." This command will display H.323 signaling messages for call setup and teardown, as well as media negotiation and other related messages. This information can be useful in identifying issues with the call setup process, such as misconfigured dial peers or issues with network connectivity.
Option B, "debug H.225 asn1," is used to display the ASN.1-encoded H.225 messages, which are used for call setup and teardown between H.323 endpoints. This debug command can be useful in troubleshooting issues with the H.225 protocol, but may not provide the full picture of the call setup process.
Option C, "debug H.246 asn1," is used to display the ASN.1-encoded H.246 messages, which are used for media negotiation between H.323 endpoints. This debug command can be useful in troubleshooting issues with media negotiation, such as codec mismatches, but may not provide the full picture of the call setup process.
Option D, "debug H.225 media," is used to display H.225 messages related to media, such as RTP streams. This debug command can be useful in troubleshooting issues with media transmission, but may not provide the full picture of the call setup process.
Option E, "debug H.323 asn1," is used to display the ASN.1-encoded H.323 messages, which are used for call setup and teardown between H.323 endpoints. This debug command can be useful in troubleshooting issues with the H.323 protocol, but may not provide the full picture of the call setup process.
In summary, the correct debug command to turn on when troubleshooting call failures on an H.323 gateway via the CLI is "debug H.323 messages."
