I cannot make calls using a voice command

device supports this feature and that you have paired the Bluetooth enabled device with your BlackBerry device.

My device does not recognize names or numbers in voice commands

Try performing the following actions:

• Say the first name and the last name of your contact.

• Adapt digit dialing to improve voice recognition of numbers.

I cannot check my voice mail

shortcut key, your device calls the voice mail access number for your active phone number.
Try checking the voice mail for your alternate phone number.
