Certkiller just installed CCM to replace their entire corporate phone system. The CEO entered his home phone as a speed dial, 9483329. However the phone call is not going through.
What is the most likely cause?
A.
The number has been corrupted in the memory of the phone.
B.
The CEO has not been added to the user directory so speed dial is not available.
C.
The administrator neglected to add the CEO to the user directory.
D.
The number is outside the corporate network and needs to be preceded by the PSTN access code.
E.
The CCM is only responding to the first 4 digits of the number and is attempting to make a call within the network.
