[asterisk-users] implementing an intercom with asterisk
I am looking to replace the phone system at my father's shop with an Asterisk box and some Cisco phones, but one piece of the implementation is tripping me up. He has two buildings (the office, and the shop proper), separated by about 3-400 yards. Currently with the ancient Meridian system installed, there is a paging intercom (to page employees, etc) on a dedicated extension - play a loud tone, then set up a 2 way channel. Anyone got any ideas, hardware wise, on how I might implement this with an Asterisk system? Thanks, and if this isn't appropriate for this list, if anyone has a better destination for the question, I"d be quite appreciative. -j

For simple paging the bogen tamb works very well. Just hook it up to an fxs port and you're good to go.

(which I don't personally recommend!) (And if you haven't IP how are you talking to the phones between sites?) So what's to stop you from putting a Cisco phone into auto-answer mode and calling it via ths Page() application? And if a Cisco can't work in this manner, there are plenty of others that will.

On a 501, you have three line appearances so you can configure line app. two to be auto-answer and still use line app. one as normal phone, hang it on the wall for anyone needs to make a call. If you need more volume, take the headset out and amplify it. There is a lot of information on auto-answer configuration, it's a little tricky but solid once you get it. -- This message has been scanned for viruses and dangerous content by MailScanner, and is believed to be clean.

Is it on the phones or separate speakers? If it is a paging system wired into the Nortel, you may be able to reuse it via an ATA, If it's done through the phones, try http://www.voip-info.org/wiki/index.php?page=Asterisk+Paging+and+Intercom for ideas That is, once you've bridged the ethernet across the 3-400 yards. You can use fibre, wireless or Thicknet. Fibre is the most robust, wireless is the cheapest and Thicknet, well, good luck getting the parts! :-) regards, Drew -- Drew Gibson Systems Administrator OANDA Corporation www.oanda.com
