We are currently running CUCM 8.6 and we are trying to integrate 7841 phones in to our system.
I have installed devicepack8.6.2.26154-1 and 78xx-10-2-1-12SR1-4.
I added the phone and it is able to register, how ever it keeps un-registering and registering again.
I have let the phone for a week and still no staying registered.
I plug a 6941 in the same port and every thing works fine.
Thanks in advance.
