I have a centralized unity 4.0(3) server and callmanager with a few small remote offices. We are running g.729 on the wan links and g.711 on the Lan. I set up a DSPFarm on a router at the main site to do transcoding. Om the call manager I see the router registered and on the router I can see that everything seems to be ok. I want unity to only talk g.711 because g.729 sounds garbled. So I went in to the registry on the unity server and added the Key G729 Enabled=dword:00000000. Then Rebooted the server.
However it does not seem to be working whenever I call the voice mail now from a phone that is in a different region it still sounds garbled and when I do a show sccp or show dspfarm I see no indication that anything is being transcoded. Also when I press the "?" button twice I see that I am still talking g.729. Since I should be talking to the transcoder and the transcoder talking to Unity that might be right, but again I see no indication on the router that anything is happening in the transcoder.
Did I miss something?
