SIP-T19P E2 DTMF not working with g.729

I have a SIP-T19P E2 that I am trying out. My system needs to use G.729 as the codec, I have the phone set up to use RFC2833 + SIP info.

I have 3 other phones on the LAN to try out as well. Grandstream, Cisco, & Polycom. Phone works fine with audio to all other phones. However the DTMF is not working correctly. From the SIP-T19P E2, to all other phones it works fine. However when any of the other phones sends the SIP-T19P E2 DTMF, i get nothing. Nothing on the LCD, and more importantly no DTMF audio.

If i switch to inband, i can hear the DTMF, but its distorted as expected when using g.729. So how can i make it sound the DTMF tones when using RFC2833 ?
