MOH doesn't work on parked calls

Hello,
We are using Asterisk 1.4.39.1 and Dahdi complete 2.4.1 installed in a Ubuntu Server 10.04. Everything is working fine, except Music on Hold for parked calls. The parked call doesn’t listen music on hold and there is no sound while it’s parked.
There is another topic about this issue but the solution was downgrade asterisk version to 1.4.35 but we can’t do that:
viewtopic.php?f=1&t=76406&start=0&hilit=moh+park

If i stop Asterisk, stop DAHDI then start Asterisk it works normally.
Conclusion, MOH doesn’t work on PARKED CALLS when DAHDI is running.

Can you help me??
THANKS.

Howdy,

1.4 is dead.
