Is the Vocalizer for Network/NSS listening on that port? Can you nmap/telnet to that IP address on port 9200? I had no issues with using Nuance’s Vocalizer with MRCP using the mod_unimrcp module.

I started the Nuance server in mrcp mode: [0] For MRCP v1 I get [1]. For MRCP v2 (using TCP) I get [2]. For nuance nvscmdline I get [3]. The FS unimrcp profiles I used are [4] for v1 and [5] for v2. Am I missing something here?! Have anyone tried this lately? Is Freeswitch 1.6 mod_unimrcp working with latest Nuance?
