[Freeswitch-users] Orphaned calls left on FS after redirect off of FS

I have also observed that the cpu load goes up to 100% when only a
couple of orphaned calls are left without being cleared by "api hupall".

Subject: [Freeswitch-users] Orphaned calls left on FS after redirect off
of FS

 

I am using the API to manage calls as they arrive at FS from a trunk

 

I have a very simple Dial plan rule that parks the incoming call.

 

  <extension name="Trunk_02031701648">

    <condition field="destination_number" expression="^02031701648$">

        <action application="park" />

    </condition>

  </extension>

 

 

Once the call is parked via the API I first send a ringing (to keep the
originator happy)

 

sendmsg  <uuid>

call-command: execute

execute-app-name: respond

execute-app-arg: 180

 

Via the API I then redirect the call on to another PSTN number back
through the same gateway

 

sendmsg   <UUID>

call-command: execute

execute-app-name: redirect

execute-app-arg: sip:<destination>@194.0.147.16

 

The redirection works well and the originator and destination are
connected correctly.

 

But after the call has left FS I'm still left with some call debris
which I cannot clear down using 

 

sendmsg   <UUID>

call-command: execute

execute-app-name: hangup

execute-app-arg: <cause code>

 

 

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"

-------------------

 

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.

The only way I've found to remove these phantom calls is either "api
hupall",  or restart the Sip profile.

 

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.
