<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>
