I have installed a CUCM 5.1.3
It works fine except for a issue that i found. The 7911 sometimes losses the forward key. The only way that i can solve this is by deleting the phone and configure all again. This is happenning in the whole system, this is random and usually just one phone at a time.
Has this happened to anyone? How to solve this?
The phone load is: SCCP11.8-3-2S
Thanks in advance.
