<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">First off, I got my scripting languages confused. My intercept script is actually done in perl, not lua (See below).<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>

<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D">I’m trying to make my intercept script be able to intercept any call that is either ringing, or on hold. I don’t want to be able to intercept a live call. If I set “intercept_unbridged_only” it seems to me
that I will be unable to pick up a ringing call? Worth a try though…<o:p></o:p></span></p>
<p class="MsoNormal"><span style="color:#1F497D"><o:p> </o:p></span></p>
<p class="MsoNormal" style="margin-left:.5in"><span style="color:#1F497D">Chris said:
</span>That channel variable was fetched in the routing state before the lua application was executed. You can either transfer to a new extension to execute the intercept or execute the intercept in the lua script. <o:p></o:p></p>
<p class="MsoNormal" style="margin-left:.5in"><o:p> </o:p></p>
<p class="MsoNormal"><span style="color:#1F497D">If I am understanding you correctly, you are referring to the “intercept-uuid” variable I am setting in the perl script. I agree with you regarding the routing state vs. the execute state, but In the pastebin
that I posted, line 259 shows that the perl script has made its choice of what UUID to “intercept”, and in line 299, the XML dialplan actually calls intercept with the UUID the script suggested. Also, I originally was calling intercept in the perl script,
but when I couldn’t get it to work, I switched to the combo method below in a desperate attempt for success. Am I misinterpreting this somehow?<o:p></o:p></span></p>
