    MusicOnHold has extra unref which may lead to memory corruption and crash.
    
    The problem happens when a call is disconnected and you had started a MOH 
    class that does not use the files mode.  If you define REF_DEBUG and 
    recreate the problem, it will announce itself with the following warning: 
    Attempt to unref mohclass 0xb70722e0 (default) when only 1 ref remained, 
    and class is still in a container!  
    
    * Fixed moh_alloc() and moh_release() functions not handling the
    state->class reference consistently.
