I have multiple locations, each with its own SX200. I just finished installing IP Trunking between 2 sites over our 100 meg qmoe link. Previously I had a T1 between the sites (we will call the main site A and this secondary site B). Also the voicemail (AVST Call Xpress) for both sites A & B are located at site A. Both sites have their own PRI with 4 digit dialing between sites A & B. After the migration almost everything works as planned, 4 digit dialing between sites, Site B able to use 4 digit dialing into the voicemail system. What does not work is use of the message button. If a voice mail is left on a deskset (I use 4025's and 4150's) at site B, the MWI lights up but the user is unable to press the message button (they get a busy). However they are able to 4 digit dial into the voicemail and retrieve messages but the MWI does not go out...
Ideas?
