Asterisk voice contract recording

I am hoping an asterisk expert can help solve this problem. I have a working freepbx/asterisk system. I need to be able to playback announcements to a caller and have the two way conversation recorded along with the announcements. It seems easy to record a conversation and easy to payback a wav file when a dtmf key combination is pressed (I worked out how to do this).. but is seem very tricky to do both. I have tried monitor and mix monitor. The problem is either the announcement will be silence in the recording or it will not play at all to either party once recording has been initiated first. Here is the two parts of the macro I have so far ;record a call exten => s,1,Set(CALLFILENAME=${ARG1}-${STRFTIME(${EPOCH},,%Y%m%d-%H%M%S)}) exten => s,n,MixMonitor(/var/spool/asterisk/monitor/Contract/${CALLFILENAME}.wav,W(3)) ;play an announcement. exten => s,1,Playback(custom/lc2) I am hoping someone has done this before and can help me get through this problem. If someone can suggest some solutions I can try them at my end.
