Do you just specify g722 for the codec prefs on FS?  I added the items 
below and have FS set to use g722.  When I call, I see that the phone 
offers g722 and g711u and FS chooses g722.  On the phone I see g722 as 
inbound and outbound, but I don't hear anything.  I've tried speaker and 
handset and get nothing on either one.  Also, the phone doesn't show 
packets increasing even though I can see FS is playing files.  It is an 
IP600.  I switch the Polycom to offer 711u first and then g722 and FS 
chooses 711u and works fine.
