Greg, As for hardware, take a look at: http://www.vikingelectronics.com/products/doorentry/product_list.html Sites like: http://www.wantphones.com/v-door-entry.html http://www.globe-mart.com/index/c/communications_intercom_systems_viking_.htm and http://www.phonemerchants.com/secprod.html (from google search results) sell them and have prices listed. These phones come in both FXO and FXS devices. The FXO will be the "autodialer" type, or those capable of using an "automatic ringdown" line. Connect these to your TDM400P. The FXS will be those that don't address autodialing or ringdown circuits. They will mention the REN (ringer equivalence number) and require a power supply. I would suggest you setup your door phone as an "immediate=yes" line. As soon as they push the button on the door phone, it starts ringing phones in the house (maybe w/ a distinctive ring?). You answer the phone and get to talk to them (without dialing). Best of luck to you, Steve _______________________________________________ Asterisk-Users mailing list [EMAIL PROTECTED] http://lists.digium.com/mailman/listinfo/asterisk-users To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
