This firmware is for the RY-IP44. It is intended for situations where stock Barix firmware is installed on the station.
Development on this branch of firmware has ceased and the RY-IP44 is discontinued.
It is NOT intended for a stock Barix Barionet 50 and Aiphone cannot provide support for attempts to modify one to perform as an RY-IP44.
If a new RY-IP44 is needed for a site, use the IXW-MAA in its place.
