If the cluster has been rebooted after applying the device pack then please provide a parallel set of captures from cucm and the IP phone after its plugged in till the time it gets stuck on registering.

Hi,

I can see the firmware cmterm-8831-sip.9-3-3-5.cop compatible with uploaded Device pack cmterm-devicepack8.5.1.17131-2.cop  in show version shared by you.

Did u reboot the server?

[Aman Soi]

DO u have enough licenses on Cal Manager?

when u connect different model phone on same port where 8831 is connected, does that work.

regds,

yes

As you are adding the phone manually, are you assigning a DN to the IP phone as well? If not , please try and do so. As most other parts related to config and network have been covered on this post, it would be better to post the packet captures as requested earlier to get to a resolution quickly.
