You have mod_unimrcp configured to send an offer to 10.6.20.47 with an SDP that says the client RTP address is at 127.0.1.1.  The MRCP server at 10.6.20.47 replies with an SDP that says the server RTP address is at 127.0.0.1.  Make sure the client and server are configured with the correct addresses.

Also, I'm not sure if Nuance Recognizer supports JSGF grammars.

Hi

I am getting the following error when using detect_speech from dialplan with unimrcp, nuance speech server and nuance recognizer. I understand that it is the job of the unimrcp client (ie mod_unimrcp) to convert the grammar from JSGF to MRCP. Why do I not see any grammar text in the SIP trace ? What could be wrong here ?

The SIP trace : (10.60.20.25 is FreeSWITCH and 10.60.20.47 is Nuance Speech Server)

My dialplan is

                        <action application="detect_speech" data="unimrcp:nuance5-mrcp2 yesno yesno.gram"/>
                        <action application="detect_speech" data="grammar yesno"/>
                        <action application="detect_speech" data="grammaron yesno"/>
                        <action application="sleep" data="500"/>

My grammar is yesno.gram kept in /usr/local/freeswitch/grammar

#JSGF V1.0;
grammar example;
<yes> = [ yes ];
<no> = [ no ];
public <results> = [ <yes> | <no> ];
