I am running CUE 7.1.2 in 2851, trying to get it working with CUCM 6.1 cluster.
the problem is that the JTAPI subsystem do not register with CUCM, the CTI route point and CTI ports also showing unknow in CUCM. the CUCM credentail and JTAPI user credentail all verify successfully and I can import users from CUCM and create mailboxes.
similar issue was fixed by restarting the CTIManager service of the CUCM, but I think I should not have to to that, because it affects all other VoIP sites and tapi applications.
I have also tried downgrade to CUE 7.0.5, I got same issue.
