Summary:                    [patch] Prevent FXS Proslic Linefeed state from
staying in  "Forward/Reverse OnHookTransfer" during call
Description: 
Now that the 3 second click after answering the call on an FXS port has
been fixed, the side effect is that the Proslic during a call, still has
the audio signal paths still powered on.

Reading the Si3215 specs it reads that an extra ~20mA is consumed while in
OHT mode.
