The speakerphones all have microphones in them but I can never be heard when "on hook". I can page but have no intercom function. I have no manuals of any type. There is a vacant card slot labeled "OPT". Could this me needed for speakerphone operation? Could this be needed for the intercom function? | | | | Joined: Jun 2001 Posts: 10,631 RIP Admin-Founder | RIP Admin-Founder Joined: Jun 2001 Posts: 10,631 | Avcom1 The 2512501 is a 6 button standard phone. The 2512502 is the 6 button speakerphone. On you model the 501's I believe you can make a reply through the intercom hands free. (Your handset down with another extension calling you) ![[Linked Image from sundance-communications.com]](https://www.sundance-communications.com/forum/smile.gif) | | | Forums96 Topics94,273 Posts638,989 Members49,424 | Most Online5,661 May 23rd, 2018 | |
