26 years in this business, 16 working on Mitel systems. Customer I cut over to a MiVB a couple weeks ago reports they can't launch ad-hoc meetings from MiCollab. I still have the test account in the system from the cutover, test it, works fine. Do a screenshare with the user, sure enough, doesn't work for him. I do some digging in KMS, find a doc suggesting looking in some logs to verify some server settings. Server settings are fine, but I do find errors in the /server/jboss.log in the MiCollab feedback diag package that interest me. User's last name is O'Neill, and I notice the errors have the username encapsulated in a set of '. So, just for grins, I remove the ' from the users' last name. Works like a champ. After taking a minute to bang my head against the wall, I submit a ticket to tech support, which immediately gets escalated to design.
