asterisk users - Jul 2009 - How to Play IVR and Read DTMF During Active Call?

Hey, 

Is there any way to play IVR and Read DTMF during active call. 

Call Flow:
?
?? USER1(initiator)? <-----> Asterisk1 <-----> Asterisk2
<-----> ?? USER2

How I can Play IVR and Read DTMF from USER1 When both users are in active
session.

I am able to play IVR and Read DTMF from USER2, which is not required,
When Asterisk2 Receives call from Asterisk1, it simply
Dial(SIP/${EXTEN},,,M(macro1)) and execute the macro1. In macro1 I play the IVR
and Read() DTMF.

The actuall problem comes here; 
IVR is playing in USER2 side only, infact It should play on both sides.
How I overcome that oneway voice problem. Please give your sugession.
I am using asterisk 1.4 on making SIP calls in Local test environment with no
NAT issues there.

Thank you

Muhammad Faheem
