* uses the incoming RTP Stream as a timing source for sending its 
outgoing Stream..  If the incoming stream is interrupted due to silence 
suppression then musiconhold will be choppy.  So in conclusion, you 
cannot use silence suppresion.

Thanks Andre for the clarification. However, sometimes, one might not be able to disable the silence supression at the remote endpoint. 
 
I am thinking of palying the music independently by another thread which uses local timing and checks the channel state (musiconhold or not) during its running. Any comments are welcome. Thanks.
