Will other VoIP services work on a B4RN router?

B4RN's own Voice service will work on all models of router supplied by B4RN. Whilst all B4RN routers have phone ports, only those on the Zyxel models are useable for third party VoIP services. That said, use of the phone ports would be at the users risk as B4RN does not support the use of third party VoIP services and can't guarantee that any future replacement router will have a useable phone port. We would always recommend the use of an ATA for third party VoIP services.
