We upgraded our files on all of our 3300's to solve the handset headset issue a few weeks back now we are running into a issue with our TW phones. When we boot the phone directly on our network the phone receives the new firm ware no headset issues. When we make that phone a tele worker and connect to the internet the phone downloads a different version of firm ware and our headset issue is back. I thought the TW server pulled the firm ware from the 3300? Is there some here we can upgrade the firmware on the TW server I have looked through Mitels documentation but can't find anything. The software we are running on the 3300's is 9.0.3.39 and TW version 5.1.
