Yes. Only do this if you have voicemail, though, because if you do not the caller will be prompted to enter their voicemail credentials (which they probably won’t have). Use the following procedure to forward all calls directly to voicemail (your phone will no longer ring):
- Press the "More" softkey.
- Press the "CfwdAll" softkey.
- Press the “Messages” button (it has an envelope on it) on your phone.
To deactivate the Call-Forward-All, press the “More” softkey, then press “CfwdAll”. You will hear 2 beeps indicating your phone is no longer forwarded.
