Finished a multi-site VPN setup, direct VPN access between all sites, along with QoS Between all of the sites.  This project was not big, but did take a bit as the phones were sending out weird DSCP bits.  We did a number of packet sniffs along with some fancy mangling to figure it out!  But we got them going.  After the QoS was setup, we could download large files, while talking on the phone without issues. Even when a new call was established, the downloads slowed and the VoIP got the prioritization it needed!
