I have CP-7811 that I cannot get to register with our CallManager, CUCM 220.127.116.1100-10. I have loaded the device pack and the phone load to the publisher and subscriber and then restarted the TFTP service on both units. In the configuration. I have double-checked the MAC address and made sure it was input correctly. I also defined the phone load name after it wouldn't register and no change. It is picking up an ip address as well as picking up the tftp address information.
The phone display is stuck on 'Registering'.
Any help would be appreciated.
Solved! Go to Solution.
Went home Friday thinking there was something else I had to do. Lost it all on the drive home and definitely lost it on the weekend.
As soon as you said it, I had the big facepalm moment.
