[Freeswitch-users] unimrcp nuance grammar failed to load

[Christopher Rienzo]

These lines indicate the problem:

2012-04-21 01:58:01.855558 [WARNING] mrcp_client_connection.c:438 (ASR-0)
Failed to Establish TCP/MRCPv2 Connection

2012-04-21 01:58:01.855558 [WARNING] mrcp_client_connection.c:527 (ASR-0)
Null MRCPv2 Connection <17 at speechrecog>

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.
