You might even have another option: DTMF via SIP INFO

This is certainly possible, but Asterisk currently assumes that if it is 
not in the media path, it also won't be able to receive DTMF frames. 
However, if you are using SIP INFO for DTMF signaling, then it should 
'just work', since when Asterisk sees the appropriate DTMF frames it 
will cause the bridge to 'break' and bring the media path back.
