Problem in subdialog

Posted: Thu Apr 09, 2009 5:30 am
by aliasg
I am calling a small page FnMisc.aspx through subdialog that always return following three variable Status, Data, Message in my application.
But same page can't be called after I record user voice of around 1 min. See log below for error.

Steps to reproduce this issue.

1. Call through subdialog
2. Record between 1 & 2 mins(with small recording of 10 sec it works fine)
3. Assign recording variable to some document variable
3. Listen to this recording(play through document variable)
4. Call same subdialog and get bad fetch(timeout)

Any idea/help?

IVR fix for problem in subdialog

Hi,

Generally, for messages such as this:

Error fetching document http://66.135.33.9/rv-dev/RVivr/FnMisc.aspx due to Operation timed out with 0 out of -1 bytes received

that means that your IVR application server is taking too long to return the fetch request back to the IVR platform.

You should increase your IVR property, fetchtimeout, to a longer time to try and avoid this IVR error.

Regards,
Plum Support

Thats not a problem

I dont think so there is something wrong with our server or we need to increase fetch timeout. If you have noticed the log, same page is called with same namelist and there is never been a problem when this code is executed first time. We tried saving more recording file more than of 4 mb size without any problem. The issue is only reproduced when we first listen it and then try to submit that file or make any other call through subdialog.

try yourself by following the steps mentioned and you will get the problem for whatever time you specify in timeout propery.

See, same frmRecordVoice is called after listening to the recording to record again.

IVR solution to problem in subdialog

Posted: Mon Apr 13, 2009 1:51 pm

Hi,

Thanks for this information and we have been able to reproduce your IVR issue. I would recommend that you check the firewall settings on your web server. If you use a firewall between your web server and the Internet, the firewall might be keeping the persistent connection open to the IVR even though the server-side connection has already been closed.

Also, if you have IIS and the Keep-Alives are enabled, you should turn them off.

This IVR issue has also occurred in these past topics, so you may want to refer to them if you are still having problems resolving this:
