Is it OK to connect a switch or hub to a phone's access port to accommodate multiple PCs hanging off the phone? It was my understanding that a VoIP phone had an internal 3-port mac-address table, accommodating the mac-address of a single PC, the mac address of the phone, and some sort of an internal mac address. So more than one PC hanging off the phone could not be accommodated. A consultant is telling us that you can indeed drop multiple PCs off the phone via a hub or switch, but I am not convinced of this. Anyone have any thoughts on this?
