Hi Huthesha,
 
We have tested your script it is working fine for us.
Have you installed ASR and HTTP server because The recordutterance property requires an HTTP server on your automatic speech recognition (ASR) server. You must install and start your HTTP server before the recordutterance property can be supported

Thanks,
Raghavendra

Hi Huthesh,
 
Please verify ASR configuration done in Voice Gateway,If possible please let us know your running config and logs by running following commands
 
show running-config
deb voip appli vxml all
 
Thanks,
Raghavendra

Hi,
 
Thanks for sharing the running config as well as the debug logs as requested. 
 
Assuming you have set the asr server IP Address in the running config, We found few discripencies. Please modify them and give a try and it should work.
 
* In ASR server set the following configuration to the hostname addressable from
router, instead of localhost: 
 
        Server/config/NSSserver.cfg:
 
                    Server.session.ossweb.machine <ip address>
 and                server.session.ossweb.port  VXIInteger 80
 
* Also the directory where the recorded files must be saved should be same in NSSserver.cfg  and httpd.config
 for example in the NSSserver.cfg it should be 
server.session.osswfm.directory    VXIString $(NSSSVRSDK)/session
 
and in httpd.config it should be 
 
DocumentRoot "C:\Program Files\Nuance\Speech Server 5.0\server\session"
 
 
Thanks,
Anusha
