+ The result is static or white noise on the inbound (from the adapter) leg of the call.
+ This is characterised by a sudden jump in magnitude of the value of the 16 bit samples.
+
+ Here we look at the first 4 48 byte frames. We average the absolute values of each sample in the frame,
+ then average the sum of the averages of frames 1, 2, and 3.
+ Frame zero is usually zero.
+ If the end result > 100, and it usually is if we have the problem, set a flag and compensate by shifting the bytes
+ for each subsequent frame during the call.
+
+ If the result is <= 100 then clear the flag so we dont come back in here...
