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 ? 2012-04-21 01:58:01.855558 [DEBUG] mod_unimrcp.c:3433 (ASR-0) grammar failed to load, status code = 407 2012-04-21 01:58:01.855558 [DEBUG] mod_unimrcp.c:1541 (ASR-0) PROCESSING ==> ERROR Complete logs are here http://pastebin.freeswitch.org/18900 The SIP trace : (10.60.20.25 is FreeSWITCH and 10.60.20.47 is Nuance Speech Server) 10.60.20.25 -> 10.60.20.47 SIP/SDP Request: INVITE sip:10.60.20.47:5060, with session description 10.60.20.47 -> 10.60.20.25 SIP/SDP Status: 200 OK, with session description 10.60.20.47 -> 10.60.20.25 SIP Request: BYE sip:10.60.20.25:5090 10.60.20.25 -> 10.60.20.47 SIP Status: 481 Call Does Not Exist My dialplan is <action application="answer"/> <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> ]; # cat conf/autoload_configs/unimrcp.conf.xml is here http://pastebin.freeswitch.org/18899 # cat conf/mrcp_profiles/nuance-5.0-mrcp-v2.xml is here http://pastebin.freeswitch.org/18898 regards, Anita
