If it's just to duplicate the ringer and button that should be relatively straight-forward using relays and a wireless doorbell or transceiver. Sending/receiving voice would be a bit more challenging. Maybe a project for Spark.io build night? (i.e., connect the intercom to the WiFi using a Spark Core)</div><div><a href="http://swansea.hackspace.org.uk/Meetings/Next">http://swansea.hackspace.org.uk/Meetings/Next</a><br></div><div><br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Tue, Nov 4, 2014 at 12:58 PM, Paul Harwood <span dir="ltr"><<a href="mailto:paul.harwood@techhub.com" target="_blank">paul.harwood@techhub.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hello,<br>

I did mention this a while back but now it's getting a bit more desperate...<br>
<br>
TechHub has a requirement that you can probably help with when you next meet if you want. We can pay associated costs but we really need to swap our buzzer handset for a portable one or something we can attach to - a chat client - a web page - - or a n other thing that could be portable - the world is our oyster. The set we have is a BELL 801 Issue 5 - cable connecting it is CAT-5E. I don't want to break this set but rather replicate it's functionality.<br>
<br>
Could you see this as a project?<br>
<br>
Cheers<br>
