We have been tasked with deploying VoIP phones in our patient rooms at our hospital. So far we have only deployed them internally. We do use voice vlans for each floor that gets ip phones. We have a Session Border Controller in our DMZ for users that have our IP phones at their homes. A few thoughts have come up about using port security on switch ports to lock down the MAC address on the port. But windows now allows users to change their MAC address without the need for spoofing software. Not to mention the calls we would get at 2:00 am when the staff replaces an ip phone. We could use some kind of ACL on the port but it would always be changing as we deploy more and more ip phones. So we are kind of stuck. Has anyone went through this type of deployment and how did you do it? Maybe an internal SBC? Thoughts???
