Need an option for 3G/4g only. Running into issues where netgear firewall blocks ports , firewall cant be disabled in recent netgear routers. Put the Vonage adapter in dmz, one of the phone with extensions app for port forwarding. The other phones with extension app without port forwarding dont work when connected to wifi. Ability to use 3G enables users to use their unlimited data plans to resolve this issue.
