Support for the option i=any seems to be broken. However, everything should 
work normally in case DTMFs are transparently sent to the server to be matched 
against active grammars. This is the default and recommended way. So, if your 
server supports either in-band or out-of-band DTMFs, then just omit the option 
i.
