 I have not tried, but it should be possible. The simpliest way is to just
send the DTMFs of the message few seconds after answer and to hope it is
corectly received.

 In order to be sure it is correctly received you will need to make
application which will detect the ACK and kissoff signals (no DSP routines in
asterisk for this) returning a variable, which one have been received. Then in
the dialplan wait for ACK tone (1400Hz 100ms folowed by 2300Hz 100ms) before
you start sending DTMF, then wait for kissoff (1400Hz 900ms) to confirm
correctness or another ACK to repeat it.
