[cisco-voip] Upgrading CM from 4.2 to 8.6 IOS upgrade required ?

[Jason Burns]

Are you using IOS hardware conferencing, transcoding, or MTP?

In those cases I recommend upgrading IOS to something that supports the
right "sccp ccm <> version <>" command. This way you get the best support
for things like RFC2833 on your MTPs and Transcoders.

Otherwise I agree that the H.323 GWs themselves are mostly version
independent for compatibility.
