Hi, Not that I have any experience with UniMRCP in combination with Nuance ASR, however it seems to me that the MRCP server (i.e. Nuance) tells you that it did not receive any input. I believe having read somewhere that the default no-input-timeout on Nuance is 8 (s). If you want to manipulate the no-input-timeout on a MRCP request basis, I think you will have to change mod_unimrcp. You may also manipulate the global request-timout which by default is 10 (s). I bet that if you set this lower than 8(s), it is FS that will timeout . Now why Nuance is not receiving any input (rtp) I don't know. If I understand correctly from the log below you play a wav file and you want that to be recognized? Maybe you need a little bit more time between triggering the recognizer and playing the wav file? You may want to use wireshark to capture the RTP stream between FS and NUANCE.

Im using FreeSWITCH as an MRCP client to my Nuance server and what is happening is if FreeSWITCH doesn't detect any speech in around 8-10 seconds I get an input-timeout, any idea's?
