[cisco-voip] CUCM 7.1(3a) ATA Box rejected

[Reto Gassmann]

 Hello group

we plan the upgrade of our Callmanager Cluster from 4.2(3) to 7.1(3a).
We have some ATA Boxes attached to the CallManager. We tried the upgrade in
our lab and found out, that most of the ATA Boxes updatetd itself fine.
However one Box appears as "Rejected" in the ccmadmin Device Pages. I did a
factory reset, but the ATA box is still rejected.

Has anyone an idea why? Other ATA Boxes with the same HW typ are up and
running.

Thabks for help
