I made some changes to a few dozen phonesets on campus last week. I added an XMWK button as well as the class of service LMPX. The problem I've run into is that on some phones (just a half dozen or so) have an issue where the MWI won't shut off, even when all messages are cleared from the mailbox. Is there something I'm missing, maybe a CLS I've overlooked? It's very odd that it would be happening on only some phones. They are all either 2216's or 2616's, all on different line cards. Other phones of the same type and on the same line card work fine with this setup.
Interested to hear if anyone has insights into this problem, Mike
