Thanks Raghavendra! This worked great for us. Also, the doc here(http://www.cisco.com/en/US/docs/routers/access/xml/voice/quick/guide/vxml_qsg.html) does not mention about defining the SIP dial peer for MRCPv2 but your post helped us to add that as well. It may be good to add that to the doc as well. Thanks again! Regards Anupam

Hi Anupam, you need to configure mrcp v2 on the gateway.The configurations differ for mrcpv1 and mrcpv2. MRCPv1 uses RTSP protocol whereas MRCPv2 uses SIP protocol. For MRCPv1: 1. ivr asr-server rtsp://ipaddress/recognizer ivr tts-server rtsp://ipaddress/synthesizer For MRCPv2: 1. Define voice class uri voice class uri nuance sip pattern nuance@ipaddress 2. ivr asr-server sip:nuance@ipaddress ivr tts-server sip:nuance@ipaddress 3. Define SIP dial-peer dial-peer voice 10000 voip session protocol sipv2 destination uri nuance dtmf-relay rtp-nte codec g711ulaw no vad Thanks, Raghavendra

Raghavendra, I could not understand your reply. As you would appreciate, MRCP is a control protocol. So it only passes the parameters to the Recognizer in SET-PARAMS. The protocol version itself may not be deciding whether hotword is supported or not. The above error comes on the IOS platform only and is not received from Nuance server. So looks like the IOS platform is itself rejecting the hotword property. Ideally, MRCPv1 and v2 both support hotword since it is sent in SET-PARAMS to the Recognizer. Our question is that when we set the property to hotword, we get the above mentioned error on IOS. So we wanted to know if we need to do any other configuration to enable hotword support on IOS. Thanks Anupam

Hi Anupam, yes, IOS supports hotword feature with MRCP V2. Thanks, Raghavendra

Hi Raghavendra Thanks for your reply. We are using Nuance Recognizer. Actually, MRCPv1 does support hotword as per the MRCP spec. We have been using hotword over MRCPv1 for very long now. Did you mean to say that hotword is supported only on MRCPv2 on Cisco IOS? Thanks Anupam

Hi Anupam, which MRCP server you are using, i think only MRCP v2 supports hotword feature , MRCP v1 ASR server does not support this feature. Thanks, Raghavendra

We tried to user bargeintype=hotword property (as mentioned in the VXML 2.0 spec) but we got the following error: 1845573: Jun 4 06:18:13.018: //656//AFW_:/vapp_asr: grammar_id=session:field2503@field.grammar grammar_id=session:field2504@field.grammar 1845574: Jun 4 06:18:13.018: //656//AFW_:/vapp_asr: encoding_name=N/A 1845575: Jun 4 06:18:13.018: //656//AFW_:/vapp_asr: xml_lang=en-US [b]1845576: Jun 4 06:18:13.018: //656//AFW_:/vapp_asr: hotword not supported[/b] 1845577: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_vapp_asr: CALL_ERROR; http://192.168.10.60:8080/test-hotword.vxml at line 11: fail with vapp error 23 1845578: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_formitem_select: loop cnt=0, 1845579: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_load_immediate_done: sidp->status=A 1845580: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_throw_error_session_event: async_status=A 1845581: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_event_proc: : event=error.unsupported.property.bargeintype status=0 1845582: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_expr_eval: expr=(var _event='error.unsupported.property.bargeintype') 1845583: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_expr_eval: expr=(var _message=undefined) 1845584: Jun 4 06:18:13.018: //656/E5ED6E5980AB/VXML:/vxml_default_event_handler: use default event handler [b]1845585: Jun 4 06:18:13.018: //656//AFW_:/vapp_session_exit_event_name: Exit Event[/b] [b]error.unsupported.property.bargeintype[/b] We are using : Cisco IOS Software, 2800 Software (C2800NM-ADVENTERPRISEK9_IVS-M), Version 15.1(4)M3 Cisco 2851 (revision 1.0) with 247808K/14336K bytes of memory.
