Web Service response are delayed on CVP VXML Application

[hari chandran]

Hi All, 

We are integrating CVP with external web Service. When we provide an input its hitting the WS but taking delay to get the response say 10, 15, seconds each time when we make a test call. However getting the success response after the delay period.

The same functionality is working fine on test application. Any one faced this issues?

How do you really tested that the response is coming only after 10-15 seconds? Maybe there's an issue with the application that is sending the request to the WS.

I prefer always to open Wireshark on the CVP server and see what happens real-time. See when the request went out, and when the response came in and see if there's really 10-15 seconds between them. If so, try also to use your browser (IE, Chrome, etc) and put the web service URL, and see if it is also takes that amount of time, and if so, it is probably an issue with the coding of the web service itself (like for example, trying to query a very big database with a bad written SQL query without indexes, and etc).

So please try the Wireshark first. It can give us a clue of how to investigate it further.

Hi Salvik, 

Thanks for your reply, please find my below observation-

Yes the response is coming after 10  or 15 seconds after we punch in the input. A silence will be there during those period, getting response after that.

In the application logs also we see the response and request has 10 or 15 seconds gap. 

But the same Webservice is working fine on test application , SOAP UI and Web browser too. 

Not sure what could be the difference in both application.

What's different between the test and the real web service? Different server/web site? Different criteria (looking up based on ANI vs. customer number for instance)? Different database logic as Slavik mentioned behind the scenes? 

If you call the same service from both systems and look up the same account, what happens?
