<p class="MsoNormal">Hi,</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I’ve been asked to integrate our CM 7.1(3) with an
iStar Pro system which controls electric strikes on doors. They want to be able
to unlock doors from an IP Phone. Let’s say a visitor’s at the
front door for me, so he lifts the IP Phone right by the door and dials my
number. Then, I input a code or a softkey or anything that will trigger a
relay, which will unlock the door.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">I absolutely don’t know how to do this. Any advice will
be greatly appreciated!</p>
<p class="MsoNormal">Regards.<span style="font-size: 10pt;" lang="FR-CA"></span></p>
