Jampet:
Do you have the documentation? Do you have access to this? There are more the just 3-5 ports - theres a lot of them.
"kwbMitel" is treating you as a "Mitel Certified Tech." Mitel does a "decent" job in documentation, and an even better job in providing Knowledgebase articles. We are train to understand Mitel wants to make things easy, so the "everyday" issues and how-toos are documented and provided to us. Mitel also trains us to see how the actual architecture works, not just the features and how to program them. For example, we learn how call-control works and how the TDM bus talks to the IP bus. When you finish your exam, you not only understand how to program the system, yet you know how the actual software and hardware work together - which in all honesty makes troubleshooting easier.
Mitel only asks us to read the documentation and if then we can't get it, we call them. Don't take it personally. Remember, this group is here to help, and the Mitel ladies and guys on this board are really-really knowledgeable. The top 5 or 6 MVPs in this group and very, very knowledgeable.
