Let asterisk dialplan do it’s job and process the call. Manage this either through the AMI events and call your scripts from there or if you are using an asterisk version that has ARI then allow it to do your call set up and tear down. Either way don’t over complicate your dialplan. <br><br><div id="AppleMailSignature">Nathan Kirk</div><div><br>On Dec 27, 2017, at 4:03 AM, Dovid Bender <<a href="mailto:dovid@telecurve.com">dovid@telecurve.com</a>> wrote:<br><br></div><blockquote type="cite"><div><div dir="ltr">My issue seems to be that I am using local channels.

<div dir="ltr">Hi,
<div><br>
</div>
<div>I have a dial plan where I need to notify an external
system when a call was answered and when the call hung up. In
both requests the start time needs to be the same. My Dialplan
looks something like this:</div>
<div><br>
</div>
<div><br>
</div>
<div>[outbound]</div>
<div>Exten => _X.,1,Dial(SIP/${<a href="mailto:EXTEN%7D@1.1.1.1" target="_blank">EXTEN}@1.1.1.<wbr>1</a>,,U(call-answer-from-carrier)<wbr>)</div>
<div><br>
</div>
<div>Exten => h,1,NoOp(ANSWERED_TIME: ${ANSWEREDTIME}
>>> DIAL_TIME: ${DIALEDTIME} >>>
HANGUP_TIME: ${EPOCH} >>> ANSWERED TIME
${MATH(${EPOCH}-${ANSWEREDTIME<wbr>},int)})</div>
<div><br>
</div>
<div>[call-answer-from-carrier]</div>
<div>Exten => s,1,Noop(CALL WAS ANSWERED AT ${EPOCH}</div>
<div>Exten => s,n,Agi(some_script.py)</div>
<div><br>
</div>
<div>Now in theory the hangup time of the call (${EPOCH} in the
h extension) minus the answered time should be the same as the
noop from my subroutine. I am finding that some times they
match and some times they are off by a second. My issue is
that the external system expects the answered time to the same
for when we call it from the SubRoutine as well as from the h
extension. I assume the difference is based on the microsecond
of when we look at EPOCH how DIALEDTIME is rounded.</div>
<div><br>
</div>
<div>Any tips on how I can get the same answered time across the
board?</div>
<div><br>
</div>
<div>TIA.</div>
