This guide details the configuration for SonicWALL routers.
Use these resources to get started:
Recommended Configuration Changes
- Verify that WAN Interface is receiving a public IP Address
- In the VolP Section > Settings > General Settings > Check the box for Enable Consistent NAT
- Ensure the SonicWall has enough resources to perform Deep Packet Inspection if you are going to use it, or disable DPI for voice traffic
- Disable SIP ALG
- In the Security Service Section > Intrusion Prevention tab > uncheck the Prevent ALL checkbox for low priority attacks (known to cause voice quality issues)
- You will need to build an Outbound firewall rule for Weave Traffic using our FQDN that will be provided during onboarding
