[Freeswitch-users] Choppy sound with PCMU

[Michael Jerris]

This is keeping track of a place in the music on hold so your hold  
music does not start back up at the same place every time.  If you  
don't want to do this it is a module that you don't need to load and  
you can get your moh from any soundfile at your choice in configuration.
