When an engineer try to pull log from an cisco EX90 codec for call setup issue using "log ctx sip packet debug 9" nothing happen, how to enable this debug?

The web interface provides access to previously captured diagnostic logs but does not enable real-time debug log streaming to a CLI session.

Changing the verbosity to 'all' adjusts the log level but still does not activate the output stream to the terminal - the log output enable command is still required.

SSH access provides the shell needed to run commands, but simply connecting via SSH does not activate log output; the log output enable command must still be executed separately.

On Cisco TelePresence TC/CE software endpoints like the EX90, setting a log context and level does not automatically stream output to the console. The engineer must run the log output enable command (such as 'xcommand log putout on') to activate real-time log streaming to the active SSH session. Without this step, the debug configuration is applied but no output is produced.
