Hi, I was OOO, maybe I lost some steps.


- Did you try to modify the failing grammar file (PRODUCTION) in order to mirror the good one (DEVELOPMENT) ? Does that work ?

- No errors on the trace ?

Note: See the attached picture where to locate the used JRE/JVM on the OD

Hi.

The '#' is the default terminating character (TermChar) for DTMF inputs.
If you want the '#' be part of a grammar, you need to change the termination character to something else in the Property item.

Try to

- Drag&drop a Property item into the node;

- Set a different TermChar
Take a look at

https://www.devconnectprogram.com/site/global/products_resources/avaya_aura_orchestration_designer/support/faqs/index.gsp?tab=general&accordion=faq-34

This explains how to add /change the TermChar.
Valid values are the numbers 0 through 9 and the star/asterisk "*" key;

- Create a static DTMF grammar recognizing the character "#' as a digit.

- (Optional) If you want to change the 'interdigittimeout' and 'termtimeout', consult the VXML spec for more info: http://www.w3.org/TR/voicexml20/#dmlATiming

Hi.

So the issue is with OD 8.1.2 with Java 11, right? Java 1.8 works.

Did you check if the Tomcat is using the JVM 11 ?

Here the screenshots showing the two full paths mentioned by John.

Hi Narmatha, got your ticket, we are going to continue there then I'll update this thread.

The second log ( grammar on the MPP) seems the mirror of the first one using 127.0.0.1 instead of the remote IP Address.

I see the same three events PAVB_00165, PAVB_06003 and PAVB_03335

The VXI (VoiceXML interpreter, a main component of the MPP) by default caches all documents that are fetched.

You can see here:

It seems the VXI/MPP is not able to open the cache for fetching the grammar:

- Did you check all MPP logs (ex. Session Manager logs) to see if there are error messages ? You can also use the log viewer on the EPM web interface (Home -> System Maintenance -> Log Viewer).

- Did you enable the trace then collect logs ?

On the EP 8.1.2 downloads

https://support.avaya.com/support/en/download/1399855686067?productId=P0407&releaseId=8.1.x

I don't see changes related to this problem, anyway feel free to update the EPM to 8.1.2.0.0377 and the MPP to 8.1.2.0.0399.

Ricardo, unfortunately no luck. No useful info on the Avaya documentation and articles so I have no answer for your request. If I get a solution/workaround, I'll update this thread.

I found a suggestion related to the 'Krypton only' as follows.
The Nuance suite 11.0.4 allows to use the 'Krypton only' but, in this case, the EP 7.2.2. and 7.2.3 can experience an MPP core dump (basically the MPP can crash). How to fix:

- move to the EP 8.0 + (the latest 8.1.2 is strongly recommended);
- install the patches EXPPORTAL-3422 (for the EP 7.2.2) or EXPPORTAL-3492 (for the EP 7.2.3);
- use 'Krypton and NLE'.

Ok, got them:

- 'nlps-audio-only=true' to activate 'Krypton only'
- Nuance ASR without NLU

I can try to investigate a bit, stay tuned.

Hi Ricardo.

- "we only can configure the same session.xml for an application, and so we will have to send the same session.xml every time":

I searched on the documentation but nothing useful, it works as design.

- "pass different values for a specific vendor parameter in different Prompt and Collect nodes":

The FAQ 'How to include vendor- specific parameters in the MRCP ASR/TTS resources allocation process? ' (https://www.devconnectprogram.com/site/global/products_resources/avaya_aura_experience_portal/support/faq/index.gsp?tab=asr-tts&accordion=faq-3)

states

"NOTE: The Voice Portal does NOT support inserting vendor specific parameters in any location other than the ones mentioned above"

you can see on the picture attached to the previous post.

What different values are you passing ? Are you using different speech servers (ASR-TTS) from the same vendor ?

Hi, as you already stated, the problem is the Apache Neethi.jar file, that is the WS-Policy framework for Apache Axis2 (https://cwiki.apache.org/confluence/display/CXF/WS-Policy+Framework)

Please, take a look at this old thread:


https://www.devconnectprogram.com/forums/posts/list/0/26092.page#p166785

Hi.

- "Is it possible to send different session.xml depending on the place of the application where the request is made ?"

I'm not aware of something similar.

The session.xml file is sent to the speech server for each app containing parameters in order to supersede the vendor-specific parameters specified on the app webpage (on the attached picture an example with a customized session.xml file for the ASR server only).

HI, take a look at this thread:

https://www.devconnectprogram.com/forums/posts/list/18855.page

Basing on your description of the issue

In 8-10 percent of calls, an error occurs - “Failed to load grammar from URL.”

and the error messages

Fetching fresh copy of http://kz-aep.xxxxxxxx:8080/UIVR_all/data/english/grammars/oneKey-srgs.grxml from server|kz-aepmpp02.kar-tel.local####
...
Failed opening cache entry for URL http://kz-aep.xxxxxxxxxxxxxxxxxxxxxx:8080/UIVR_all/data/english/grammars/oneKey-srgs.grxm


the root cause can be a network problem, ex. network instability (connection unstable going up and down even if the ping is working).

Because the issue happens while fetching a copy of the grammar, please double-check also the fetch timeout in the MPP server (see attached pictures for the exact location on the EPM web interface), the default value is 15 secs.

Concerning your last question, are you referring to an external grammar ? It is possible to set an external grammar on the OD app, take a look at
