I just placed an order for wall mount kits for the SBX 4024-00 phone model. The one I always order is 3866-71, however our rep at Graybar says that part number is no longer valid. Does anyone know if there is a new part number for this?

Use the same number as the wall mount kit for an Edge 700 phone, it cost less and its a better mount. VW-E700WM-24
