Weave phones work well with Cisco ASA firewalls. There are several important settings to verify that the ASA is configured correctly.
Use these resources to get started:
Recommended Configuration Changes
- Ensure ASA is NOT inspecting traffic for SIP, RTSP, IP-Options, or DNS
- Verify that WAN Interface is receiving a public IP Address
- Set up Traffic Shaping/QoS (we use DSCP 26 (SIP) & 46 (Real-Time Media)) to prioritize voice traffic
- You may want to build an Outbound firewall rule for Weave Traffic using our FQDN that will be provided during onboarding
