-No, a SIP phones cannot connect to Asterisk voicemail using G.729 if you do not have a licence. You will need a licence for at least one channel to do this.
-DTMF is not related to the codec itself or how it works, however, inband DTMF is not recommended on compressed channels due to the possibility of distortion. Outband is the way to go as the tones are capture and then regenerated locally.
Inband signaling is achieved thought the telephony voice channel, while outband is through some other type of communication channel. In the case of SIP it is the INFO method.
Hope this helps,
