Help. I'm just about to bail from Verizon on this one.....

I have terrible outgoing call quality. My voice sounds muffled, almost like (to quote one Verizon rep.) like I'm talking underwater.

Verizon has replaced my Razr Maxx and the SIM card. The issue shows up on BOTH phones. However, when my number is forwarded to another cell phone (AT&T) there are no voice quality issues either way.

Incoming voice sounds great. Outgoing voice is terrible, regardless of who initiates the call. This began about the middle of May in Austin Texas. Every single call is affected. I've checked to make sure the noise canceling mics are clear, as I know that can make a difference.

Does anyone have any thoughts at all?
