I'm configuring an IP Office 406 w/2 Digital Station 30 mod's and 1 Analog 16 mod. I'm using a mixture of 6400 and 4400 series phones. On the 4400 series phones, I have one problem, and that's that the DTMF tones are skewed. It's almost like the phones are using ALaw instead of MuLaw. Any ideas? I've racked my brain and can't think of anythign else to try.
