>> Also, did you configure the codec to be used between each site and the HQ in Regions?  We recently installed 8.5 and I noticed when the codec was set to "64 kbps (G.722, G.711)" the codec actually used on the call was G.722 and it sounded terrible.  I had to go into CallManager service parameters and set "G.722 Code Enabled" to disabled.  After this, the calls sounded fine.
