Yes, as is clearly documented on the wiki :-)

No, because you cannot use inband DTMF with G.729 anyway. Since you will 
need to be using out-of-band DTMF (RFC2833 for SIP, or the only method 
on IAX2), then there is no issue with decoding the G.729 audio stream.

Note that you will not be able to monitor/record calls without G.729 
licenses, nor will you be able to play any audio files that are not 
already in G.729 format.
