Hi,
 
I just wanted to know how do we arrive at the session
timeout value of a CallStudio application?
 
In our application we are using the modular approach, where
in the control shall be passed by subdialog invoke to other module. And I
wanted to know if the Module A passes the control and caller spends more time
than the configured session timeout (of module A) in module B - will this have any
impact on releasing the VXML Port or what will be the impact?
 
Is this session timeout value equivalent of the Tomcat Session
value?

I do not know the answer but what you could could easily test is edit the properties of application "A", General Settings, and change the session to 1 minute.  Then change the setting in application "B" to 2 minutes.  Then call in and spend more than one minute in Application "B" and see if it times out at 1 minute which then you can assume the root application controls the overall session timeout.  Unless Application "A" gets suspended I would "think" it controls the overall session timeout.

Few  things on timeout based on what I have seen in prod systems. A session timeout of 3 mins is good.  A session timeout of 1 min may be too short and could cause the application to abort unecessarily in case of any delay. You could always set it to higher value like 10-30 mins. However what happens is that if you have any errors, say some random bad fetch errors that app could hang for the session timeout value. So if you set it to 5 mins, aftter the bad fetch I have seen the application sometimes not exiting for the session timeout value. It could potentially hold the port for that much time.
This is based on some random bad fetch errors I have seen here and there.

I believe that the Session Timeout must be longer than the duration of the invoked subdialog application. If necessary, you can write some custom java to change the session timeout value before invoking the subdialog, and then change it once you return. As Hemal mentioned, occasionally something might cause the application to abort and leave the VxmlServer port license 'hanging' - in this case, the license isn't freed by VxmlServer until that Session Timeout expires. So you don't want it too long. In general, it should be a bit larger than the max length of time it takes any "voice" element (collecting input from the caller; or SubdialogInvoke) to complete.

Thanks all for the suggestions.

Couldn't respond to this thread as forum's webpage gave "you dont have sufficient privileges" (off the topic)

I did experimentetd the various session timeout values as Hemal suggested with about 2-3mins.  Most of the time this configuration works fine, however there are cases i have noticed in our lab that some calls gets suddenly dropped at parent application as session timeout(as per config. time), without giving any trace about the invoked application's state. No activity logs to understand this better. I am currently worried of giving a greater value as it can cause potential port blockage in production environment in case of some delay/error..

Janine,

let me incorporate your suggestion in my application and post the result

I  have seen similar random occurences in lab and sometimes in prod env also and it may not matter even if you were to increase timeout.  It may still happen at higher timeout values. Also have seen some random badfetches. Which version  are you using ? Cisco had ruled out any app or vxml server issues.  Possibly something at the gateway level. Don't have a resolution yet.

We are using CVP 8.5.

In all of our previous applications, we held the call control is purely with ICM. But in this case since call control is partially held by CVP - its causing the worry

I have seen similar random timeout issue in 8.5.  However the occurrence is less than .001% of the calls.  Based on logs,  I have seen something on gateway side. If you see a higher percentage, you may need to look at other things including your app.
