BVoIP has developed custom Fanvil X4 phone templates that are available to use for BVoIP Partners.
The device has gone through preliminary testing and is working properly with BVoIP on V14 of Cloud PBX.
This is the 3rd Fanvil model now "supported" in addition to the Fanvil X3 and X5.
You can find a full list of our "preferred" devices here.
If you are a BVoIP partner you can submit a request for access for our support team.
