We've setup UCM 6.0 and UC Connection 2.0 in our lab. Everything is working except we hear no sound when we attempt to loginto voice mail. I believe everything is setup correct on UCM and UC. During testing, we can call an extension, see that call goes to voice mail. We hear no greeting message, just dead air. We talk for 30 seconds or so (intending to leave voice mail). Shortly after MWI lights up on destination phone and see vm waiting icon on line. Any ideas why no sound is present?
