"Callback on busy"

I’m trying to implement “callback on busy” in my dialplan and I’d like to have an IVR to interactively choice ‘5’ to be recalled when destination hangups or ‘9’ to leave a message in voicemail.
Actually, I have this macro in my dialplan (only derived from Trixbox but I can freely edit it) to call a local extension:

exten => s,1,Macro(user-callerid)
exten => s,n,Set(FROMCONTEXT=exten-vm)
exten => s,n,SetCDRUserField(to-internal)
exten => s,n,Macro(dial,${RINGTIMER},${DIAL_OPTIONS},${ARG2})
exten => s,n,GotoIf($["${CHANNEL:0:5}" = “Local”]?s-${DIALSTATUS},1) ; if the channel is Local, then
do not go to voicemail. This is primarily to avoid vm for call-forwarded extensions in ring groups
exten => s,n,GotoIf($["${ARG1}" = “novm”]?s-${DIALSTATUS},1) ; no voicemail in use for this e
exten => s,n,NoOp(Sending to Voicemail box ${ARG2})
exten => s,n,GotoIf($["${DIALSTATUS}" != “BUSY”]?NOCB)
exten => s,n,GotoIf($["${MACRO_CONTEXT}" != “from-internal”]?NOCB)
exten => s,n,Set(DB(CallBack/${ARG2})=${CALLERIDNUM})
exten => s,n(NOCB),Macro(vm,${ARG1},${DIALSTATUS})
exten => s-BUSY,1,NoOp(Extension is reporting BUSY and has no Voicemail)
exten => s-BUSY,n,GotoIf($["${MACRO_CONTEXT}" != “from-internal”]?NOCB)
exten => s-BUSY,n,Set(DB(CallBack/${ARG2})=${CALLERIDNUM})
exten => s-BUSY,n(NOCB),Busy(20)
exten => _s-.,1,Macro(outisbusy)

Here I simply set an ASTDB record but I’d like to have an IVR as described.
Can I have an IVR in a macro? Can someone give me some good suggestion?
