> If you configure two spans in your system, and setup a native bridge with the span that isn't the master, it's possible for repeated/missing "chunks" to appear in the bridged data stream.  This appears due to the master span processing taking place asynchronously with the audio received on the the span that you're actually interested in recording from.
> ****** STEPS TO REPRODUCE ******
> Install a card in the system, load dahdi_dummy and configure it to use kernel timers then load the driver for the card in the system.  Use dahdi_monitor to record from the hardware span and look at the spectral plot of the recording.  You will see strong harmonics that aren't present when the master span isn't dahdi_dummy, but instead the board that you're recording from.
