Hello, Just joined the forum, and for a very specific question. Ill start off apologizing that this is not directly cyber related. Anywho, I am an ISSM and a physical security guy asked if I could help him find an intercomm for our new building. We have a service window and he would like to have an intercomm that actively listens on the lobby side, but allows us to hit the PTT on our side to talk out. He wants to avoid users having to hit a PTT on their side. So does anybody know of a vendor that has something like that? I cant seem to find it on my own, or havent come across it yet. Needs to be hard wired, no wireless allowed at all. Any help would be really appreciated!
