Hello Arsen,

As part of a Proof of concept, we have been testing the interoperability of the Google Dialogflow plugin with Cisco CVP solution. Our set-up comprises of the Cisco CUCM, Cisco Virtualized Voice Browser (VXML gateway) and Cisco CVP Vxml Server. We checked the interoperability with both MRCP V1 and MRCP v2 and Cisco is able to establish communication with  UniMRCP in both versions.

We have the VXML page hosted on the built-in tomcat of the Cisco VXML server. We have updated version of the sample VXML application that was provided by you as we don’t have TTS. We have disabled the default grammars in Cisco by setting the property universals = none. 

However when we place a call, the call fails every time with a “Gram Load Failure” from UniMRCP.  While we have specified <grammar src=”builtin:speech/transcribe”/> in our VXML application, we noticed that Cisco treats this as a SRGS grammar and appends the URL of the VXML application to ”builtin:speech/transcribe” and for every call, the grammar sent by Cisco to UniMRCP is “http://<VXML app url>/ builtin:speech/transcribe which is not recognized by UniMRCP and sent back a Gram load error. See snippet below.

We kindly request your help on this since it from your post it looks like the GDF plugin should work with VXML platforms from Cisco, Avaya, Genesys.

We have attached the following logs for reference. Your assistance will be greatly appreciated to take this Proof of Concept to conclusion. This would lead us to position this solution for some of our clients.

1)    Unimrcp server logs .
2)    Cisco VVB logs.
3)    VXML file.
4)    UnimrcpServer.cfg

This message is intended for everyone trying to use CVP with UniMRCP server having either GSR or GDF plugins loaded.

While some of you seem to have addressed the problem with the built-in grammar, I would provide a general solution, which should work with other IVR/VoiceXML platforms having no ability to reference an arbitrary built-in grammar.

The idea is to accept any SRGS XML speech grammar without implementing the actual processing. While this approach is not semantically correct, it will allow to easily resolve the problem without any noticeable drawbacks.

Interested parties may install a development version of the GDF plugin. The binary package is built for Red Hat/ CentOS 7 and can be installed as follows:


Note this is a temporarily location and the package might be deleted in a week or so without a notice.

The new version accepts a speech grammar with the content type "application/srgs+xml" or "application/grammar+xml", specified either in DEFINE-GRAMMAR or RECOGNIZE requests. HTTP URI reference is not supported.

No configuration or any other changes are required on UniMRCP server side.

Please give it a try and let me know the results.

The same will be available for GSR plugin...

Thank you so much, Arsen. I'll give it a try and let you know. Just wondering, whether this is currently available for GSR as well?

Not sure about CVP defaults, but the MRCP header field Media-Type is normally controlled by the VoiceXML property recordutterancetype. You may set that property to "audio/x-wav" from your VoiceXML application.

Yes I saw that. I am trying to do this on recognize context, rather than record. Does google not support, "audio/basic"?

That property applies to recording user utterances while attempting recognition.

Check Section 7.1 in particular.

Thank you, Bharath, for your quick feedback.

I guess the only difference between your working and non-working examples are in the number of SRGS grammars referenced per RECOGNIZE request.

Please note that only one speech and/or one DTMF grammar can be activated.

Not sure if I was clear enough, but SRGS grammars are not actually processed. The change that I have made simply accepts an SRGS grammar to be able to employ recognition via the MRCP framework. The rules specified in the grammar will not be honored, as Google Speech-to-Text API does not require or accept grammars.

The above error most likely has nothing to do with CPV integration. You may need to verify your Google account credentials to make sure the corresponding API is properly enabled. Also, check the time on your server. If the time is not properly synchronized then TLS connection to the Google service may fail.

Hello Arsen,

We wanted to give an update post our testing with CVP/ IP IVR on the updated plug in package you have provided for both gsr and gss.

As pointed by you, we are sending only one inline grammar within the VXML app. Infact we have used the same app that Bharath had informed as working.

While the "DEFINE GRAMMAR" request is completed sucessfully, in RECOGNIZE, UniMRCP server sends back unsupported grammar format. There is no other description for failure. No new grammars are sent as part of RECOGNIZE and Cisco is referring to the content id of the grammar "sent as part of DEFINE GRAMMAR in the RECOGNIZE request.  Please see the snippet below  and the UniMRCP server logs and unimrcpserver.xml for reference.

Could you kindly check why there is an issue here? 

Do you think it could possibly be the nomenclature of Cisco's conent-id which ends in a .grammar  (session:fie...@field.grammar)?

Hello Sukumar,

Content-id may contain an arbitrary string and should not cause any issues.

I took a quick look at the provided logs. The problem is most likely in the content of RECOGNIZE requests.

Content-Length: 32

session:fie...@field.grammar

While the supplied actual content contains 28 visible characters, the Content-Length is set to 32. This means there are some trailing hidden characters, which are interpreted as an additional grammar reference and cause the problem.

Of course, the plugins can be further enhanced to be able to skip any trailing whitespaces. However, for the time being, you may need to figure out how to properly compose such a content from CVP, as others did.

Thanks,  Arsen, for your explanation. I really appreciate the change that you made on the GSR, GDF plugin side to allow SRGS grammar.

Hi Arsen,

Is there any possibility to convert the srgs grammar to speech context form so that it could be passed as built-in grammar to GSR to get better interpretation? 

For example:
 SRGS grammar:
<grammar type="application/srgs+xml" root="r2" version="1.0">
               <rule id="r2" scope="public">
                  <one-of>
                  <item>visa</item>
                  <item>master <item repeat="0-1">card</item></item>
                  <item>amex</item>
                  <item>american express</item>
                  </one-of>
               </rule>
  </grammar>

Speech Context:

 <speech-context id="r2">

         <phrase>visa</phrase>

         <phrase>master card</phrase>

         <phrase>amex</phrase>

         <phrase>american express</phrase>

      </speech-context>


Builtin form
   builtin:speech/r2

Hi Bharath,

That is a good idea. I thought before about such an option to implicitly compose a speech context based on the provided SRGS grammar, but did not have the chance to take a closer look.

I believe you are aware of, but in case others are not: a user speech context can be dynamically specified via the DEFINE-GRAMMAR request as demonstrated in Section 6.3 of the Usage Guide. This option may not be applicable to CVP, though.

Hi Arsen,

It's good to know that you have thought about this idea before. It would be really great to have such an option so that most of the IVR related applications could make a way with Unimrcp SR plugins. 

Cheers,
Bharath

Sukumar, Did you ever get your issue resolved? I am running into the same thing and Arsen's response doesn't really help as I don't think we have control over that message.

I think you have to make sure the grammar attributes need to be added. Namesapce language etc.

Hello Arsen,

As part of a Proof of concept, we have been testing the interoperability of the Google Dialogflow plugin with Cisco CVP solution. Our set-up comprises of the Cisco CUCM, Cisco Virtualized Voice Browser (VXML gateway) and Cisco CVP Vxml Server. We checked the interoperability with both MRCP V1 and MRCP v2 and Cisco is able to establish communication with  UniMRCP in both versions.

We have the VXML page hosted on the built-in tomcat of the Cisco VXML server. We have updated version of the sample VXML application that was provided by you as we don’t have TTS. We have disabled the default grammars in Cisco by setting the property universals = none. 

However when we place a call, the call fails every time with a “Gram Load Failure” from UniMRCP.  While we have specified <grammar src=”builtin:speech/transcribe”/> in our VXML application, we noticed that Cisco treats this as a SRGS grammar and appends the URL of the VXML application to ”builtin:speech/transcribe” and for every call, the grammar sent by Cisco to UniMRCP is “http://<VXML app url>/ builtin:speech/transcribe which is not recognized by UniMRCP and sent back a Gram load error. See snippet below.

Mohan, can you provide a bit more detail? I am trying to use a common Form element and I am setting the Voice Grammar to "builtin:speech/transcribe" as per all of the documentation I have read.

Kristian,

This and other fixes are available in GSR 1.8.0 release published today. Also note that the corresponding version of RPM and deb packages is 1.5.7.

I understand that the version numbers might be confusing, but there is a logic behind.

There are separate version numbers maintained for each component the server and individual plugins. However, the binary RPM and deb packages of plugins are made for a specific version of the UniMRCP server.

For instance, the package version 1.5.7 indicates the 7-th release of GSR plugin made for UniMRCP server 1.5.



has this fix been applied to the 1.7 GSR plugin currently available for general download?

Everyone who installed the development versions of the GSR and GDF plugins, please consider removing the development RPM package first and then proceed with the regular installation/upgrade.

rpm -e unimrcp-gsr-1.5.7-1.el7.x86_64
yum install unimrcp-gsr

or

rpm -eunimrcp-gdf-1.5.5-1.el7.x86_64
yum install unimrcp-gdf

This is required since the dev and the released packages have the same version numbers.

Please re-evaluate the released version with CVP and provide feedback.

Thanks.

Seems like gateway is timing out. Which timeout should i increase. I have tried a few and did not work.

Based on communication with several parties, I believe, yes.

Following the provided logs, SIP and MRCPv2 message exchange seems correct. However, I doubt that any RTP packets reached UniMRCP server. Here is the log statement indicating a start of RTP session

2018-08-05 13:55:43:243478 [INFO]   Open RTP Receiver 10.190.66.196:5000 <- 10.184.120.139:27666 playout [50 ms] bounds [0 - 600 ms] adaptive [1] skew detection [1]

There is a similar statement for closing RTP session "Close RTP Receiver". This log statement contains the number of RTP packets/octets received and is printed at the end of MRCP session. Check it out.

Make sure the local RTP port range is properly mapped. Your client and server are on different networks.

Hello All,

Has anybody gotten it work with Cisco CVP?

I am testing GDF (latest version) with Arsen's TestDialogFlow.vxml file. When I call in, I can hear the welcome audio i.e., "Welcome to DialogFlow. How can I help you?". After this part, GDF is capturing my input and responding back. But the response is not getting played. Instead, it just disconnects.

Below is the one that plays Welcome prompt

Thanks for the reply, Mohan.

I have enabled MRCP logs in GW. Heres what I found. I am running UniMRCP in Ubuntu 16.04. I checked in the server, there is no folder with the name "utterances". What could be the problem?

Hi Vamsi,

Oct  8 23:48:00.713: %HTTPC-6-CONNECT_FAILED: The connection to server 0.0.0.0 failed

You would need to disable recording of utterances from the VoiceXML app

   <property name="recordutterance" value="false"/>

or install and configure an HTTP server on your Ubuntu 16.04 to allow CVP to fetch the recorded prompts.

Otherwise, the MRCP message flow is correct and I do not see any issues.
