A unique learning experience I encountered a few months ago….
Lesson Learned:
Be careful how you configure your end Be careful how you configure your end user’s H.323 systems. You never know user’s H.323 systems. You never know what you might be EXPOSING your users what you might be EXPOSING your users to.to.
