Proper setup for voip

FTINC

I use 3cx for off site voip pbx. What is the proper setup to make sure voip traffic going through the watchguard is prioritizing voip traffic, please be specific. Below is my current setup.

Firewall -> Aliases
Name: Voip
Members:
Host IPv4: (pbx public ip address)
FQDN: (pbx public dns address)

Network -> SD-WAN
Name: Voip
Method to route traffic: Failover
Interfaces: (add internet interfaces in order for voip traffic)

Firewall -> Policies
Name: Voip
Policy Type: Voip - tcp = 0, udp = 0
Settings - From: Any-Trusted
Settings - To: Voip (alias)
SD-WAN - SDWAN Action: Voip
Advanced - QoS - Override: Checked
Advanced - QoS - Marking Type: DSCP
Advanced - QoS - Marking Method: Assign
Advanced - QoS - Value: 46 (EF)
Advanced - QoS - Prioritized traffic based on: Custom Value
Advanced - QoS - Value: 5

Firewall -> Policies

• disable policy auto-order
• set Voip policy to order 1

Besides throughput thought the firewall, you need to consider your how full your Internet link is - which may well be a bigger issue.

You can set up a Traffic Management action for your voip policy to guarantee bandwidth for it.

You can set the TM action to: Per policy, Max bandwidth = 0, Guaranteed bandwidth to your goal - such as 5 Mbps.

I would select the TM action for both Forward & Reverse on the policy. For an outgoing policy, Reverse will attempt to make the desired bandwidth available for traffic on the link from your ISP to the firewall.
