<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">We’re doing a show with a phone that needs to ring on stage. I have an old Tele-Q box that works so I can make the ringer work. Now the director would like to have audio from
one of the other characters coming through the handset speaker. I have a pretty good idea of how to make this work but I have a couple of questions of the hive mind to see if I have all bases covered. If there is a device for doing this that would be the
best solution.</span><o:p></o:p></p>

<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">I’m planning on using the black and yellow wires to run audio to the speaker and reconfiguring the phone so the handset speaker isolated to those wires only. </span><o:p></o:p></p>

<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">Does this sound like a good plan?</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">Tele-Q will only be used to make it ring, when handset is pick up it stops the flow to the ringer.</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">Isolating the handset to the other lines should keep the tele-Q and audio system separated</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">Do I have a danger of the 90vac from the tele-Q and the audio signal running along the 4 conductor phone line ?</span><o:p></o:p></p>

<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">Running both signals through 4 conductor phone wire</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt"> </span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">I’ve run audio to speaker phones before but that was always through a separate line. Should I run a separate line for audio so the phone ring and audio don’t interfere with each
other.</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">I’m also concerned 90v would do bad things to the audio console so I may run a separate system just to feed the handset.</span><o:p></o:p></p>
<p class="MsoNormal" style="text-autospace:none"><span style="font-size:11.0pt">This effect is only a couple of minutes long so it’s a lot of work to make it practical.</span><o:p></o:p></p>
