If they are older 2500 type sets, they are most-likely high-voltage (70-90 volts) neon message waiting lights. I haven't seen any SIP devices (or anything IP for that matter) which will light those suckers up. If the MWI "flickers" with the ringing of the phone, it's a high-voltage neon type MWI. The high-voltage lights were standard on PBX's for 30 years or more. --Shane ---------------------------------------------------------------- This message was sent using IMP, the Internet Messaging Program. _______________________________________________ --Bandwidth and Colocation provided by Easynews.com -- asterisk-biz mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-biz
