6945 not registering in CUCM 8.6.1.21015-1

[UC Support]

Hi

I have the 6945 IP Phones (fw 9-1-1-0)they get the TFTP even they upgrade to 9-2-1-0, but after that they don't register with CUCM.

Do I need to install the enabler

cmterm-6945-qed.9-1-1-0.cop.sgn

to make it register??

I have successfully register 6941 with CUCM 8.6.x and I never installed the enabler. But don't know if it should be different with the 6945

Thanks

Carlo

Installed the enabler and plugged a new phone with comes with the 9.1.1.0 and is register
