I need help configuring a remote office firewall to allow great Voice over IP.  I have configure the QoS Port Based Settings to Port on the LAN interface that the VOIP phone is on which must connect to a Hosted PBX system.  I have set it to the Highest Priority then have configured CoS traffic forwarding queues to highest (4) for CoS priority 5, 6, 7 and selected the proper interface.  I am not very savvy with VOIP CoS prioritization and I could really use some help to figure out how to provide the best VOIP quality on this small 1 computer, 1 VOIP phone office sitting behind a Cisco RV215W router which connects to a Broadband modem and is seeing 10Mb down and 1 Mb up.  Bandwidth management is set to  a lower upstream and downstream 850k up and 9500 down. and I have enabled SIP service TCP and UDP 5060/5061 High Priority on both upstream and downstream.  I am attaching some images of the settings page I have and have turned on logging informational

Thanks SouthMod.  I guess I'll have to make a call in to Cisco.  I'd be happy to turn over the points if I could get some guidance of any kind.

Is your VoIP phone set to mark the packet with DSCP value 46 and have the switch trust the DSCP value? Is your PBX hosted on-site or hosted?

A 2007 NCSA Cyber Security survey revealed that a mere 4% of the population has a full understanding of firewalls. As business owner, you should be part of that 4% that has a full understanding.
