[cisco-voip] IP Precedence and IPSec

[su1droot]

Hello,
I have a problems that I can't seem to find any documentation either
way on.   We are running voice over a GRE/IPSec tunnel.  I know when a
packet is encapsulated in a GRE tunnel the IP Precedence bits are
copied on to the GRE packet, but I am unable to find any docs that say
if the Precedence bit is copied outside an IPSec packet.  Does anyone
know if it does or does not copy this bit?  I'm guessing it does not.
