We use G.711MU for our larger sites and G.729A for our smaller sites.

I've noticed headset issues as well with new IP phones. The new AWH55+ wireless headsets seem to work great. I've had a few issues with the old plantronics headsets. If replacing the batteries didn't help, I would adjust all settings on the headset until it sounded better. Some, I just had to upgrade.

I'm just thinking outloud here. I'm sure you've already tried these suggestions. I have been fighting static and cell-phone-like quality for a few months now myself.

The biggest issue we were able to resolve, that helped tremendously, was our network QOS policies and COS settings from our end and ATT's end. We made voice traffic priority 1 and made sure our BW settings were the same.

Probably not much help, but thought I would throw a few things we did to get better quality.
