I have a couple SPA302 now registered on the SPA9000. So far I can not firgure out any way to tranfer a call to other extentions from the cordless handsets. Ideally I would like to use shared line or park if there is a way to impliment it. (I am using sla on the SPA509G's) . I have been waiting for something to replace the WIP310 and was excited to see that the SPA232D will support the SPA9000, but they arent much use if they can't integrate with the rest of the system
