We've got a new customer that has called us after they got tired of their Avaya recommended vendor in Texas. They recently upgraded from 8 to 11, and since then the T1 connection to a Mitel phone system at another building no longer works. I've checked the licensing, and the new licenses are valid. Our contact at our supplier is not being much help with this, and the customer is already getting tired of me not knowing what's going on here. Nothing changed other than the upgrade. I'm going to see if he has a backup of the config prior to the upgrade and compare is to what it has now. Any other ideas here?
