Replies hotevent not working in VVB

Hi All,

We are migrating to CVP 11.6 VVB, we are configuring vxml property within the application, in our current cvp 9.0 environment when we set the above tts vxml property the tts request is sent to appropriate tts server. However in cvp 11.6 when we set the tts server in the application using the above vxml property the tts request not sent the tts server that is set in the application.

As per the cvp 11.6 documents the above tts vxml property setting is appropriate and can be used in cvp 11.6.

Did anyone use the tts vxml property to set the tts server in the application in cvp 11.6 VVB ? Any suggestions  much appreciated.

Thanks in Advance

I just tried it on my 11.6 and it seems to work, however I used rtsp:// (ie, using the Nuance IP address, instead of en-us-tts)

But, I've installed patch 81 on the VVB to fix some vvb errors (however, patch 81 has a bug where you'll no longer receive notification of missing audio files)


Cisco VVB 11.6(1)ES81 - addresses many ASR and TTS problems. But as I mentioned previously, you'll no longer get notified of missing audio files if you install it. So, if you need the missing audio file notifications, you may want to wait for the next patch.

Hi Janine,

We have installed VVB ES81 patch.

We are using MRCPV2, so we are using the syntax sip:<tts-hostname>@<TTS IP Address> is the syntax correct?
Currently even though when we configure a wrong ttshotname and ipaddress still the tts request works.

Thanks in Advance

This always worked since 11.5 and nothing to do with ES81. But I believe alternative text for a prompt had an issue in ES80.


"" can be set to sip:tts@hostname

Continuing with the above example:

1. Add TTS server (use hostname instead of IP)

2. Add dns entry for hostname should be added through CLI.



Hi, using VVB 12 w CVP 11.6 and not having any luck with the sip:asr@host approach to flip between asr/tts devices on an application by application basis.  Using the root doc properties:  Anyone else have luck or different instructions then above notes?  Thanks

Hi !

No, at this moment you cannot change(override) VVB tts/asr-server via VXML Property, like for IOS VB. It's looking like the programmer didn't give us this option by design.

I add Piyush, may be him add something new.
