Dear Anthony and Brian,

 

Firstly please accept my apologies for wasting your time. Brian’s  request for the SVN number prompted me  to realise I was running with an out of date version of FS.

When I synced up to the head of the trunk and reran my tests the scenario I described below worked perfectly with no stuck calls.

 

Therefore the sequence Park, Ringing (ring back), Redirect  using the event API has provided me with the automated redirection I was seeking.

 

Thank you for your advice earlier this week and prompt turnaround of fixes for the problems I encountered with bridged and deflected calls.

 

Regards

I have tried to reproduce this issue but haven't been able too... What SVN Rev are you on?

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”

4 total.

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

 

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.
