*77 Feature not working (System Record)

I'm using the latest Asterisk 1.4.13 and FreePBX 2.3.1.0 and I cannot use the *77 feature to record system messages.
If I go to the "System Recordings" tab in the web UI, the page displays the following error after I enter my extension number:

"Using your phone,dial ** MISSING FEATURE CODE ** Start speaking at the tone. Hangup when finished.and speak the message you wish to record."

 

I try dialing *77 anyway, and I get the message "That feature is unavailable".

 

Solution:

 

Change the system record to something other than *77. I use *44 and it works fine.

 

And it's also the same doing about the *99, (review record function)
