CVP VXML Server encountered an Application Hangup error

[manojkumar.vunnava]

Hi,

I have a simple script where it plays a 2 option menu and then it plays an audio for each option and then hangs up in CVP itself. When I choose option 1 or 2 it doesn't play the audio file and just hangs up with below error, but however the activity logs shows normal disconnect. Does anyone faced this issue before? Appreciate your time in helping me.

Just to add my findings.

I have replaced the "Hang Up" node with CVP Sub Dialog Return" and it worked fine. It played the audio file after choosing the option in menu and disconnected gracefully. What would be the difference in using Hang up and subdialog return node?

I really don't want to send the call back to ICM though it really doesn't make any difference either way.

[manojkumar.vunnava]

One of the cisco document says that Hang up element should be preceded by a subdialog_return. But there will be no exit state for subdialog_return element. So wondering how it could be done.

 Error Code 42 -- App Hangup This is returned to Unified CVP if the Hang Up element is used without being preceded by a Subdialog_Return element.

What CVP model you are using? is comprehensive call flow model where CVP is controlled by ICM?

[manojkumar.vunnava]

Hi Chintan,

Yes, in my contact center model CVP is being controlled by ICM. I can solve my problem by send the call back to ICM and cna hang up over there. But I just want to know in which best scenario can I use hangup element in CVP.

[Chintan Gajjar · Accepted solution]

For VXML standalone deployments you can use hangup to end your call flow. 

[Aydin.armagan]

Hi

we use standalone deployments and same error when it used hangup

[Aydin.armagan]

Hi All

I have replaced the "hang up" node with CVP Sub Dialog Return" and but not work.

Anybody solve this problem?

[Chintan Gajjar]

What is your call flow here?

[Aydin.armagan]

Hi 

we are call fow below ,

we are listening welcome prompt , cannot  put any select after retry runing prompt. maximum retriy equal 3 and then hangup.

But we analiysed debug vxml on Voice gateway . hangup after application error and redirect running survive application 

[Chintan Gajjar]

This is not the call flow i am talking about, i am looking for more CVP level call flow.

like call hits Ingress gateway and from there what happens?

[david.macias]

As a best practice you should have ICM do all the routing, this includes ending the call. Send ICM something like status=end and then have ICM end the call. It will save you headaches in the future.

You are right David. I usually like ICM to do all the routing but what's best case scenario to use hangup element in CVP?
