I'm going to have to go with Aerowinder on this one.
I had problems with 4.1.1 call quality on every ROM I used a custom kernel on. When I hit 4.1.2 all of the call quality problems just disappeared out of thin air. You could also update your bootloader with the MD5 firmware script (search for it) and flash a different modem like MD5.
And once you update if you're looking for a problem free kernel, I'd try the newest stock kernel from AT&T, MG2.
