Realspeak TTS configuration with GVP 8.1.6

[mumtazalam2k]

I am setting up a Realspeak TTS 4.5 with GVP 8.1.6.
I have configured the MRCP Proxy and Nuance (TTS) Resource Access Point in GVP 8.1.6.
On the Nuance TTS end, I have setup the NSS (Server & Client) and RealSpeak TTS.
Tested RS TTS using the client provided by NSS and it is generating a sample TTS file.

However when I call into a test VXML application on GVP, the MCP is giving an erorr message as shown below.

Any clues what I am doing wrong.

I think that you have to add connection to the Resource Access Point for TTS on MCP object which will use the TTS. Could you check this?

[mumtazalam2k]

Yup, I was missing the connection on the MCP object.
Thanks a lot.

Do I also need to specify the format for the wave file that is generated and to be played by the MCP (i.e. the VXML application) as the TTS generated could not be heard in the call?

I have not done any wav file format modifications in the NSS or RealSpeak TTS side.

infact I can see the following warning errors in MRCP Proxy logs.
NOTE:- I am able to successfully telnet from GVP Server to RealSpeak TTS Server on port 4900.

The MCP logs though do not show much of an error as shown below.

Just for info sake, the NSS Logs shows as TTS Request as success.
