No Music On Hold with FreePBX 2.4.0 on Asterisk 1.6

As anyone did some experimentation with FreePBX and Asterisk 1.6? Everything seem to work find except MusicOnHold, what are the required settings to make MusicOnHold work? Here is what I have verified so far.

Both incoming and outgoing routes have Music on hold set to default.
The user reference by the incoming route has Music on hold set to default.

I did the following tests with a sip client.

  1. Answer an incoming call from trunk.
  2. Put the call on hold, no music
  3. Dial an external number while still having incoming call on hold.
  4. Switch to incoming call, no music on outgoing call.
  5. Switch back to the outgoing call, still no music on the incoming call.
  6. Hang-up incoming call, still no music on outgoing call.
  7. Hang-up outgoing call.

While doing this tests I was looking at the Asterisk console and did not see any SetMusicOnHold call in the trace.
Did I miss something? Any suggestion will be appreciated cause am out of idea now.
