Greetings list, We have a client with an analogue door intercom/opening unit which we're attempting to replace with an IP variant. The existing unit has the following functionality:
1) Intercom - visitor hits "call", talks to operator 2) Door opening - operator can open the door by dialling a 4-digit PIN followed by * (the door unit interprets the DTMF tones) 3) Door opening - the door unit has a numeric keypad to enable approved persons to enter by entering the 4-digit PIN on the keypad We've tried getting the existing unit working with an ATA, but it's only about 50% reliable (hangup not always detected, DTMF not always detected, etc.), so it's probably time to look at fully IP alternatives. Any suggestions gratefully appreciated. Regards, Chris _______________________________________________ -- Bandwidth and Colocation Provided by http://www.api-digital.com -- AstriCon 2008 - September 22 - 25 Phoenix, Arizona Register Now: http://www.astricon.net asterisk-users mailing list To UNSUBSCRIBE or update options visit: http://lists.digium.com/mailman/listinfo/asterisk-users
