Hi All,
We are using MS OCS 2007 R2 and MOC 2007 R2.
Everything has been working beautifully for a couple years and suddenly we are getting "No Phone System connection, the Call control server is temporarily unavailable"
all SIP: and TEL: URI information is correct, CCM is correct and licesned for CUPs, and deskphone controll is enabled.
SDI traces indicate the user is being authorised properly.

SIP/2.0 200 OK
the only thing that has happened is that the user re-imaged the laptop with windows7-64bit. We also have about 30 users in an office that was recently migrated onto WIN7. Phone integrations works for 50% of them, but the rest have this issue.
Has anyone encountered this issue before. We are also using the same SOE and all in the same AD container with same GPO's
