Hello All,
We are running CUCM 8.5 and we meet a problem here:
We have a Phone (let's name it P_A) in site A, we set CFA of this phone to a external mobile, then the result is as below:
1. Call internally from Phone_B in site A -> OK
2. Call internally from Phone_C in site B -> Busy tone
3. Call from external mobile -> Busy tone
We also tried to set CFA to Phone_D in site A, the problem is still the same.
Does anyone have any idea about this?
Thanks.
Savi
