After you have run the VoWLAN Voice Readiness Tool in WCS 7.0, you see there are potential problem areas in your facility. Which two actions will help you troubleshoot these coverage areas? (Choose two.)
A.
Verify the green, yellow, and red regions in the RF environment only if the floor has not been calibrated.
B.
To prevent one-way audio, set the AP power levels to half the power of the client. This will ensure proper radio coverage.
C.
You need to edit the RSSI values for Cisco IP Phones so the 802.11b/g/n radios display the region map properly.
D.
Determine if the coverage area will have enough APs to support the VoWLAN client, since all APs must have a Tx power level that does not exceed that of the client.
E.
Set the AP power level to match the VoWLAN client to avoid one-way audio.
