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. We tried switching to g.711 and it seemed to help a little. anyone else experience this?

I'll answer myself. Opened a case with TAC, and they confirmed that it is a bug, CSCsz68389. They provided a newer firmware that fixed the problem. I hesitate to call it newer because the version is actualy 8.4.(4)ES7, while I was running 8.5.2s.

Yeah, they sent me a link to go get it. It was password protected and what not. Probably will have to open a TAC case to get the file.
