Unfortunately, as stated on certificates on an older post.
THIS CERTIFICATE IS ONLY VALID TO THE EXTENT HOLDER IS EMPLOYED BY AN AUTHORIZED MITEL DISTRIBUTOR PERMITTED TO SELL, INSTALL, AND MAINTAIN PRODUCTS FOR WHICH INSTRUCTION HAS BEEN SUCCESSFULLY COMPLETED.
You can still work on the product same as customers do, however not certified and no product support.
Also unless the customer has an agreement for software assurance through a Mitel VAR no access to AMC = no free upgrades or adding licenses.
