We just bought a brand new 7821 Phone and wanted to test it internally in our labs.
We´ve downloaded the COP file mentioned in the Release Notes (cmterm-78xx.10-1-1-9.cop.sgn), restarted TFTP Service, even restarted the Server, but there is still not a single 78xx phone type showing up under the Phones list.
We have tested with the following versions:
The release notes state it should work with versions 8.5+.
Am I missing something? Do we need an additional package to make it work?
I think you need to install new device pack to enable new device support in cucm.
This link will help you to find the compatibility matrix . - http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/compat/devpack_comp_m...
Cucm 9.1 dev pack do not support 7821 , so you need to download for 8.6 at this link - http://software.cisco.com/download/release.html?mdfid=283782839&flowid=4... and test it.
Note- after installation cluster wide restart necessary.
Please rate if this help.
