not after it rings, before it ring a forward key works. to disconnect a conf call the "goodbye" (rls) key comes to mind. the csd key disconnects parties one at a time.. to drop one person from a call.. if your setting up a conf and 1 station goes to mail, press the cfd, keep the conf drop that one user..
i use bfs keys for pa's.. they press it once and forward the boss's set to them... so take my calls stops ring in the big office
