Have a new deployment going on. running CUCM 7.1(2), phones are 7965 and 7945 with 8.5.2s firmware. Using g.722 codec. When someone raises their voice, or the person just naturally speaks loud, the other person hears a lot of crackling or scratchy sounds. Happens both through speakerphone and using the phone.
