<p class=MsoNormal>I am using the API to manage calls as they arrive at FS from
a trunk<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>I have a very simple Dial plan rule that parks the incoming
call.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal> <extension name="Trunk_02031701648"><o:p></o:p></p>

<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Once the call is parked via the API I first send a ringing
(to keep the originator happy)<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>sendmsg <uuid><o:p></o:p></p>

<p class=MsoNormal>execute-app-arg: 180<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Via the API I then redirect the call on to another PSTN
number back through the same gateway<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>sendmsg <UUID><o:p></o:p></p>

<p class=MsoNormal>execute-app-arg: sip:<destination>@194.0.147.16<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The redirection works well and the originator and
destination are connected correctly.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>But after the call has left FS I’m still left with
some call debris which I cannot clear down using <o:p></o:p></p>

<p class=MsoNormal>Using command “api show channels” I find
the following held on FS The only way I’ve found to remove these
calls is “api hupall”<o:p></o:p></p>

<p class=MsoNormal>-------------------<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The SIP signalling is correct with an outgoing “302
moved temporarily” [with the new destination in the contact] which is
then Ack’ed by the switch. From a SIP point of view the call no
longer on FS.<o:p></o:p></p>
<p class=MsoNormal>The only way I’ve found to remove these phantom calls
is either “api hupall”, or restart the Sip profile.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Any suggestions on how I can remove these phantom calls
without recourse to “api hupall”. “api hupall”
kills any incoming calls as well as the stuck calls.<o:p></o:p></p>
