Advice for VOIP shaping in multi-LAN environment

[oddworld19]

Thanks for your time. I wanted get your input on the specific traffic shaping schedulers/algorithms that I should consider. I'll outline my goals and then provide an overview of my network.

Goals

Primary goal:  Prioritize VOIP traffic. I have a home VOIP line and AT&T microcell. The call quality gets destroyed during heavy internet use. I would expect no more than 4 concurrent users.

Secondary goal: De-prioritize VPN traffic (although, I am willing to skip this goal if it would over-complicate things).

My Network

• Current release of pfSense x64

• Supermicro SYS-5018A-FTN4 with 16G ECC ram

• 2x Juniper ex2200, "stacked" in a virtual chassis

• Comcast, consumer grade internet (130 mbps down, 12 mbps up). Pings to 8.8.8.8 average 20-30ms.

• Single physical WAN interface, although there are two gateways (one for OpenVPN traffic, and one for everything else)

• "LAN" side of traffic:

–--- 4x front-facing interfaces are bundled in LACP to Juniper ex2200 switch

----- LACP bundle is a trunk of 7 VLANs; VLANs are given separate "logical" interfaces within pfsense

----- One of the VLANs exclusively carries the desired VOIP traffic

----- One of the VLANs exclusively carries traffic bound to the OpenVPN tunnel

Summary

I would appreciate your input in creating the following:

High Priority: VLAN with VOIP traffic

Middle Priority: Regular traffic

Low Priority: VLAN with OpenVPN traffic [although, we can skip this priority level, if it would over-complicate things]

Thanks for your time.
