CUCM 6.1.2.1000-13
Unity 7.0.2
What is the latest firmware release I can upgrade to for reliable operability using:
7911/12
7940
7960/7961/7961G
I successfully upgraded to 8-3-4SR1S on all existing phones, but now when I attempt to add a new phone to the system I recieve the error:
SCCP 41.8-5-2SR1S
AUTH FAIL
Should I roll back to a 8.4.x release?
