Call Quality today

I have a ticket open, but I wanted to see if anyone else has experiencing less than good call quality on outbound calls today? I have never had bad quality audio since day 1, but today outgoing calls sound watery, like a bad cell phone or a g729 codec or something. Incoming calls sound good like they normally have. I notice when my wife calls me at work from the house, and others she has called also noticed.

I had a STUN server in my configuration which they took off. After I rebooted the calls are much better. I don't know if the STUN server can interfere with audio quality, or if rebooting fixed things, or if it is all just a coincidence! I had been on the STUN for a couple of weeks without problems.
