Call Waiting Problem

I just upgraded from 1.2.17 to 1.4.5 and it seems that call waiting is activated on all polycom601s that are connected. My agents needless to say are not happy about the tone in their ear. In my extensions_additional file I have *70 activate and *71 deactivate along with include=>app callwaiting ect. I can dial both and get the automated attendant to say activated/deactivated however it is not executing. Am I missing a file somewhere that I need to call? Any help is greatly appreciated, Also can I just remove the tone so that they dont hear one? Thanks

I wish I could say I was posting RESOLVED call waiting problem but I am still working on this. I am using Fedora Core6 with Asterisk 1.4.5 and Free PBX 2.2.1 maybe some more information will help here is my ect/asterisk/extensions_additional.conf file
