I just upgraded ccm to 3.2.1. Unity remained at 3.0.3. I upgraded the tsp to 6.0.1.<br><br>All functionality remained the same except users can't login to Unity to check their mail. The symptom when they either press the messages button or * out of the main greeting and enter their ID from an ip phone or pstn phone is this: silence for about 6 seconds, then Unity hangs up. Call viewer says everything is coming through correctly. The direct routing rules did not change during the upgrade. Nothing changes if I add a direct routing rule that expressly sends someone dialing from their extension to unity to 'attempt-sign-in. On ip phones the phone Tx count is rising, but (obviously?) the Rx count remains zero.<br><br>
