Have a strange problem. Brand new office setup with all new Yealink T46S phones. When adding an extension to be a member of the call queue and have that extension receive the voicemail messages for the queue it breaks the message waiting display indicator for voicemail on that extension's Yealink T46S. After doing this the MWI doesn't function properly. Even after taking the extension out of the queue, or deleting the extension/user. I have a ticket open with support but they haven't been much help. Any ideas?
