<DIV><FONT face=Arial size=2>I have a customer that has recently upgrade to UCM
6.X from 3.X and they are running Unity 4.0 in HA. When they are on the Primary
Unity server. After a while Unity will not pickup. Call to unity will Ring and
Ring. The customer will fail to the Secondary and everything works fine. All the
Voicemail ports are registered and the TSP is 8.3 on both servers. I can't see
any issues in the Integration. Has anyone ran into a similar issue. Any help
would be appreciated.</FONT></DIV></BODY></HTML>
