VOIP and Codewords on HFC

I'll make it short and sweet!  I have a customer that has a 6Mb P2P connection over our HFC network.  They're utilizing the circuit for Prioritized VOIP traffic and stated they are using DSCP. They also use the circuit for their general data. Our network is seeing ~.0065% Correctable CW's, and 0% Uncorr CW's.

My main question for voip and codewords is:  How is the VOIP traffic affected by Correctable CW's in general?  WIll the VOIP service drop those packets that were corrected by FEC regardless as they come in due to the small increase of latency/jitter?

Thanks for any insight to this matter in advance!
