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

I don't think there was anything that successfull though... I have to say though - if you have such an integrated unit that needs nothing more than an analogue connection (and power, presumably), I'd love to know the make - for me, (or rather one of my clients) it would be worthwhile trying to find an ATA that would work with it.. Got a name/website for the opener device? Gordon

(1) is naturally trivial. As for sending the actual signal to open and close the door: that may take a separate out-of-band operation. e.g. System(/usr/sbin/open-sesame) But what about typing the PIN? "Hello, you have reached Treasure Cave Inc. If you know the access code, dial it now. If not, press 0 for the operator." The point is to separate communication from door opening. Both are different problems to solve. I'm not sure you will gain much by bundeling them together. -- Tzafrir Cohen icq#16849755 jabber:tzafrir.cohen at xorcom.com +972-50-7952406 mailto:tzafrir.cohen at xorcom.com http://www.xorcom.com iax:guest at local.xorcom.com/tzafrir
leave the existing keypad there. as for integrating it with asterisk. use an ata with 2 FXS ports. one FXS port connect to a viking door box http://www.vikingelectronics.com/ and set the ATA to do hotline on it. that door box is a regular analog phone in the shape of a door box that when call is pressed it goes offhook hence the requirement of hotline mode. it also has auto answer that when you call the box it goes off hook automaticaly. then use a relay from http://www.mikesandman.com/ that gets activated on ring connect that to the second FXS and that will unlock the door.

Your using a Linksys right? you can use the fxo port and send DTMF.
