That's right (I wrote it). For a detailed description check also
the CONFIGURATION file in asterisk-oh323 package.

It seems that you haven't enabled the logging of debug info
(check logger.conf and add the "debug" option in the line
"console => ..."). Anyway, the debug of the OH323 channel driver
is basically for debugging and not tracing a call.

 From the messages above it is obvious that: 1) there is a gatekeeper
somewhere in the path, 2) you try to contact a non-existent user.

Your Dial string is just fine.
