We're running CUCM 11.5 SU2 (184.108.40.20600-21) and installed the latest devpack (cmterm-devicepack220.127.116.1183-1.cop.sgn) in order to use the 8832 Conference Phone. We've just configured our 8832 and while the device comes up, and I can place calls from it, in the CUCM Web Admin GUI the status shows as none/none, as if it has never registered.
Has anyone seen this? I checked around and found bug ID CSCvj33740 but it doesn't seem to match in that we get a DHCP address, and it appears to be up and working from the user side.
I think it may actually be this bug;
Further to Rob's reply, I've experienced the exact same thing with another new device pack on 11.5(1)SU2 and yes, a reboot of the cluster fixed it (not sure if a Callmanager service restart may have fixed it also but it was easier to just reboot in my case).
The documentation may be inaccurate in some places which is something that's going to be addressed eventually. You need to reboot the cluster in order the device pack to be applied correctly, which should resolve your issue.
